Here’s a step-by-step breakdown of the process: + +1. **Data Streaming**: The extension initiates a stream from the source collection, reading documents one by one. +2. **In-Memory Buffering**: Documents are collected into a buffer in your computer's memory. +3. **Bulk Write Operation**: Once the buffer is full, the extension performs a bulk write operation to the target collection. This is more efficient than writing documents one at a time. +4. **Continuous Cycle**: This process repeats - refilling the buffer from the source and writing to the target - until all documents from the source collection have been copied. + +This method avoids loading the entire collection into memory at once, making it suitable for collections that are moderately sized. + +## Important Considerations + +### Not a Snapshot Copy + +The copy-and-paste operation is **not an atomic snapshot**. It is a live data transfer. If documents are being written to the source collection while the copy process is running, it is possible that only a subset of the new data will be copied. This feature is best used for moving smaller, relatively static datasets. + +### Large Collection Warnings + +Because this feature streams data through your local machine, it can be slow and resource-intensive for very large collections. To prevent accidental performance issues, the extension will show a warning for collections that exceed a certain size. + +You can customize this behavior in the settings: + +- **`documentDB.copyPaste.showLargeCollectionWarning`**: (Default: `true`) Set to `false` to disable the warning entirely. +- **`documentDB.copyPaste.largeCollectionWarningThreshold`**: (Default: `100000`) Adjust the number of documents that triggers the warning. + +> For more details on handling large datasets, see the section on [For True Data Migrations](#for-true-data-migrations). + +--- + +## Step-by-Step Guide + +The process is guided by a wizard that adapts based on your target, providing two main flows. + +### Flow 1: Paste into a Database (Create a New Collection) + +This flow is triggered when you right-click a database in the Connections view and select `Paste Collection`. + +#### Step 1: Large Collection Warning (Optional) + +If the source collection contains a large number of documents, a warning dialog will appear first. + +> This warning can be disabled or its threshold adjusted in the extension settings, as noted in the [Important Considerations](#important-considerations) section. + +#### Step 2: Name the New Collection + +You will be prompted to provide a name for the new collection. + +#### Step 3: Confirmation + +A final summary is displayed, showing the source and target details, including the new collection name. You must confirm to start the operation. + +### Flow 2: Paste into an Existing Collection + +This flow is triggered when you right-click an existing collection in the Connections View and select `Paste Collection`. + +#### Step 1: Large Collection Warning (Optional) + +If the source collection contains a large number of documents, a warning dialog will appear first. + +> This warning can be disabled or its threshold adjusted in the extension settings, as noted in the [Important Considerations](#important-considerations) section. + +#### Step 2: Choose a Conflict Resolution Strategy + +Because you are merging documents into a collection that may already contain data, you must decide how to handle documents from the source that have the same `_id` as documents in the target. + +You will be prompted to choose one of four strategies: + +##### 1. **Abort on Conflict** + +- **What it does**: The copy operation stops after processing the batch that contains the first document with a duplicate `_id`. Within that batch, all documents that do not have a duplicate `_id` will be inserted. Any documents inserted from previous batches will also remain. The operation is not rolled back. +- **Use case**: When you want to stop the process on the first conflict, accepting that some data may have already been transferred. +- **Example**: Target has a document: + + ```json + { "_id": 3, "data": "original-three" } + ``` + + A batch of source documents is being processed: + + ```json + [ + { "_id": 1, "data": "one" }, + { "_id": 2, "data": "two" }, + { "_id": 3, "data": "three" } + ] + ``` + +- **Result**: A conflict is detected for the document with `_id: 3`. The documents with `_id: 1` and `_id: 2` from the batch are inserted into the target collection. The copy operation then aborts. The target collection will contain the newly inserted documents and its original data. There is no automatic cleanup. + +##### 2. **Skip Conflicting Documents** + +- **What it does**: If a document with a duplicate `_id` is found, the source document is ignored, and the operation continues with the next document. +- **Use case**: When you want to merge new documents but leave existing ones untouched. +- **Example**: Target has a document: + + ```json + { "_id": 1, "data": "original" } + ``` + + Source has documents: + + ```json + { "_id": 1, "data": "new" } + { "_id": 2, "data": "fresh" } + ``` + +- **Result**: The document with `_id: 1` is skipped.

The target collection will contain + ```json + { "_id": 1, "data": "new" } + ``` + +##### 4. **Generate New IDs for All Documents** + +- **What it does**: Ignores `_id` conflicts entirely by generating a new, unique `_id` for **every document** copied from the source. The original `_id` is preserved in a new field with a prefix `_original_id`. +- **Use case**: When you want to duplicate a collection's data without losing the reference to the original IDs. This is useful for creating copies for testing or development. +- **Example**: Target has a document: + + ```json + { "_id": 1, "data": "original" } + ``` + + Source has a document: + + ```json + { "\_id": 1, "data": "new" } + ``` + +- **Result**: A new document is inserted into the target with a brand new `_id`. The inserted document will look like: + ```json + { "_id": ObjectId("..."), "_original_id": 1, "data": "new" } + ``` + The original document in the target remains untouched. + +#### Step 3: Confirmation + +A final summary is displayed, showing the source, the target, and the chosen conflict resolution strategy. You must confirm to start the operation. + +--- + +## For True Data Migrations + +The copy-and-paste feature is a developer convenience, not a dedicated migration tool. For production-level data migrations, especially those involving large datasets, complex transformations, or the need for data verification, a specialized migration service is strongly recommended. + +Dedicated migration tools offer significant advantages: + +- **Performance**: They often run directly within the data center, avoiding the need to transfer data through your local machine. This dramatically reduces network latency and external traffic costs. +- **Reliability**: They provide features like assessments, data validation, and better error handling to ensure a successful migration. +- **Migration Types**: They support both **offline migrations** (where the source database is taken offline) and **online migrations** (which allow the source application to continue running during the migration with minimal downtime). +- **Scalability**: Built to handle terabytes of data efficiently. + +### Professional Data Migrations + +The best tool often depends on your data source, target, and migration requirements. An internet search for "DocumentDB migrations" will provide a variety of options. Many cloud platforms and database vendors offer dedicated migration tools that are optimized for performance, reliability, and scale. + +For example, Microsoft provides guidance on migrating between different versions of its own services, such as from Azure Cosmos DB for MongoDB (RU) to the vCore-based service: +[Migrate from Azure Cosmos DB for MongoDB (RU) to Azure Cosmos DB for MongoDB (vCore)](https://learn.microsoft.com/en-us/azure/cosmos-db/mongodb/how-to-migrate-vcore) + +Before starting any significant migration, it is important to perform a thorough requirements analysis. For critical or large-scale projects, seeking professional help from migration specialists can ensure a successful outcome. diff --git a/docs/learn-more/index.md b/docs/learn-more/index.md index 18fe4bcd4..5d00ce9e3 100644 --- a/docs/learn-more/index.md +++ b/docs/learn-more/index.md @@ -16,4 +16,5 @@ This section contains additional documentation for features and concepts in Docu - [Local Connection](./local-connection.md) - [Local Connection: Azure CosmosDB for MongoDB (RU) Emulator](./local-connection-mongodb-ru.md) - [Local Connection: DocumentDB Local](./local-connection-documentdb-local.md) +- [Copy and Paste Collections](./copy-and-paste.md) - [Data Migrations](./data-migrations.md) ⚠️ _Experimental_ From a35456a4685738881d1f7af8555cc3654bb809d0 Mon Sep 17 00:00:00 2001 From: Tomasz Naumowicz Date: Tue, 16 Sep 2025 14:11:30 +0200 Subject: [PATCH 074/423] feat: linked 'learn more' content --- src/commands/copyCollection/copyCollection.ts | 7 ++++++- .../LargeCollectionWarningStep.ts | 18 +----------------- .../pasteCollection/pasteCollection.ts | 1 + 3 files changed, 8 insertions(+), 18 deletions(-) diff --git a/src/commands/copyCollection/copyCollection.ts b/src/commands/copyCollection/copyCollection.ts index 5e12f7481..70509dba4 100644 --- a/src/commands/copyCollection/copyCollection.ts +++ b/src/commands/copyCollection/copyCollection.ts @@ -3,7 +3,7 @@ * Licensed under the MIT License.

Pre-filter conflicts by querying for existing \_id values +2. Insert only non-conflicting documents +3. Return skipped documents in errors array +4. Continue processing despite conflicts + +**Note:** Pre-filtering is a performance optimization. Conflicts can still occur due to concurrent writes, handled by fallback path. + +**Example:** + +```typescript +// MongoDB API implementation +async writeWithSkipStrategy(documents) { + // Performance optimization: Pre-filter + const { docsToInsert, conflictIds } = await this.preFilterConflicts(documents); + + // Insert non-conflicting documents + const result = await collection.insertMany(docsToInsert); + + // Return skipped documents in errors array (primary path) + return { + insertedCount: result.insertedCount, + skippedCount: conflictIds.length, + processedCount: result.insertedCount + conflictIds.length, + errors: conflictIds.map(id => ({ + documentId: id, + error: new Error('Document already exists (skipped)') + })) + }; +} +``` + +### Overwrite Strategy + +**Flow:** + +1. Use bulkWrite with replaceOne + upsert:true +2. Replace existing documents or insert new ones +3. Return matched, modified, and upserted counts + +**Example:** + +```typescript +// MongoDB API implementation +async writeWithOverwriteStrategy(documents) { + const bulkOps = documents.map(doc => ({ + replaceOne: { + filter: { _id: doc._id }, + replacement: doc, + upsert: true + } + })); + + const result = await collection.bulkWrite(bulkOps); + + return { + matchedCount: result.matchedCount, + modifiedCount: result.modifiedCount, + upsertedCount: result.upsertedCount, + processedCount: result.matchedCount + result.upsertedCount + }; +} +``` + +### Abort Strategy + +**Flow (Primary Path - Recommended):** + +1. Insert documents using insertMany +2. Catch BulkWriteError with duplicate key errors (code 11000) +3. Extract conflict details and return in errors array +4. Include processedCount showing documents inserted before conflict + +**Flow (Fallback Path):** + +- If conflicts are thrown instead of returned, retry loop catches them +- Provides robustness for race conditions and unknown unique indexes + +**Example:** + +```typescript +// MongoDB API implementation +async writeWithAbortStrategy(documents) { + try { + const result = await collection.insertMany(documents); + return { + insertedCount: result.insertedCount, + processedCount: result.insertedCount + }; + } catch (error) { + // Primary path: Handle expected conflicts + if (isBulkWriteError(error) && hasDuplicateKeyError(error)) { + return { + insertedCount: error.insertedCount ?? 0, + processedCount: error.insertedCount ?? 0, + errors: extractConflictErrors(error) // Detailed conflict info + }; + } + // Fallback: Throw unexpected errors for retry logic + throw error; + } +} +``` + +### GenerateNewIds Strategy + +**Flow:** + +1. Remove \_id from each document +2. Store original \_id in backup field (\_original_id or \_original_id_N) +3. Insert documents (database generates new \_id values) +4.

Pre-filter conflicts by querying for existing \_id values -2. Insert only non-conflicting documents -3. Return skipped documents in errors array -4. Continue processing despite conflicts - -**Note:** Pre-filtering is a performance optimization. Conflicts can still occur due to concurrent writes, handled by fallback path. - -**Example:** - -```typescript -// MongoDB API implementation -async writeWithSkipStrategy(documents) { - // Performance optimization: Pre-filter - const { docsToInsert, conflictIds } = await this.preFilterConflicts(documents); - - // Insert non-conflicting documents - const result = await collection.insertMany(docsToInsert); - - // Return collided documents in errors array (primary path) - return { - insertedCount: result.insertedCount, - collidedCount: conflictIds.length, - processedCount: result.insertedCount + conflictIds.length, - errors: conflictIds.map(id => ({ - documentId: id, - error: new Error('Document already exists (skipped)') - })) - }; -} -``` - -### Overwrite Strategy - -**Flow:** - -1. Use bulkWrite with replaceOne + upsert:true -2. Replace existing documents or insert new ones -3. Return matched, modified, and upserted counts - -**Example:** - -```typescript -// MongoDB API implementation -async writeWithOverwriteStrategy(documents) { - const bulkOps = documents.map(doc => ({ - replaceOne: { - filter: { _id: doc._id }, - replacement: doc, - upsert: true - } - })); - - const result = await collection.bulkWrite(bulkOps); - - return { - matchedCount: result.matchedCount, - modifiedCount: result.modifiedCount, - upsertedCount: result.upsertedCount, - processedCount: result.matchedCount + result.upsertedCount - }; -} -``` - -### Abort Strategy - -**Flow (Primary Path - Recommended):** - -1. Insert documents using insertMany -2. Catch BulkWriteError with duplicate key errors (code 11000) -3. Extract conflict details and return in errors array -4. Include processedCount showing documents inserted before conflict +## Implementing New Database Writers -**Flow (Fallback Path):** - -- If conflicts are thrown instead of returned, retry loop catches them -- Provides robustness for race conditions and unknown unique indexes - -**Example:** +To add support for a new database, extend `StreamingDocumentWriter` and implement **only 3 abstract methods**: ```typescript -// MongoDB API implementation -async writeWithAbortStrategy(documents) { - try { - const result = await collection.insertMany(documents); - return { - insertedCount: result.insertedCount, - processedCount: result.insertedCount - }; - } catch (error) { - // Primary path: Handle expected conflicts - if (isBulkWriteError(error) && hasDuplicateKeyError(error)) { - return { - insertedCount: error.insertedCount ?? 0, - processedCount: error.insertedCount ?? 0, - errors: extractConflictErrors(error) // Detailed conflict info - }; - } - // Fallback: Throw unexpected errors for retry logic - throw error; +class MyDatabaseStreamingWriter extends StreamingDocumentWriter { + /** + * Write a batch of documents using the specified strategy. + * Handles all 4 conflict resolution strategies internally. + */ + protected async writeBatch( + documents: DocumentDetails[], + strategy: ConflictResolutionStrategy, + ): Promise> { + // Implement database-specific write logic } -} -``` - -### GenerateNewIds Strategy -**Flow:** - -1.

document provides a comprehensive summary of the work completed for implementing folder hierarchy in the DocumentDB Connections View, following a hybrid storage approach. + +--- + +## Completed Work Items + +### 1. ✅ Extend Storage Model +**Commits:** 075ec64 +**Status:** FULLY COMPLETED + +**Actions Taken:** +- Extended `ConnectionStorageService` to support both connections and folders using a unified storage mechanism +- Added `ItemType` enum with `Connection` and `Folder` discriminator values +- Changed `folderId` property to `parentId` for clearer hierarchical relationships +- Implemented migration from v2.0 to v3.0 with automatic defaults +- Added comprehensive helper methods: + - `getChildren(parentId, connectionType)` - Get immediate children + - `getDescendants(parentId, connectionType)` - Recursively get all descendants + - `updateParentId(itemId, connectionType, newParentId)` - Move items with validation + - `isNameDuplicateInParent()` - Check for duplicate names within same parent + - `getPath()` - Generate full hierarchical path +- Removed separate `FolderStorageService` for unified approach + +**Pros:** +- ✅ Single storage mechanism simplifies architecture +- ✅ Type-safe discriminator pattern prevents errors +- ✅ Unified CRUD operations for all items +- ✅ Automatic migration preserves existing data +- ✅ Helper methods enable complex operations with simple APIs +- ✅ Circular reference prevention built into updateParentId + +**Cons:** +- ⚠️ Increased complexity in ConnectionProperties interface +- ⚠️ All connections must now include type and parentId fields (though defaults are provided) +- ⚠️ Migration path adds code complexity + +--- + +### 2. ✅ Create FolderItem Tree Element +**Commits:** 075ec64 +**Status:** FULLY COMPLETED + +**Actions Taken:** +- Created `FolderItem` class implementing `TreeElement` interface +- Set appropriate contextValue (`treeItem_folder`) for VS Code integration +- Configured collapsible state and folder icon +- Implemented `getChildren()` to recursively load folder contents +- Added `storageId` property for move/paste operations +- Refactored to work with unified `ConnectionItem` storage + +**Pros:** +- ✅ Clean separation of concerns +- ✅ Proper integration with VS Code tree view APIs +- ✅ Supports unlimited nesting depth +- ✅ Efficient lazy loading of children + +**Cons:** +- ⚠️ ConnectionType needs to be tracked per folder (currently defaults to Clusters) +- ⚠️ Some code duplication in child rendering logic + +--- + +### 3. ✅ Update ConnectionsBranchDataProvider +**Commits:** 075ec64 +**Status:** FULLY COMPLETED + +**Actions Taken:** +- Modified `getRootItems()` to build hierarchical tree structure +- Placed `LocalEmulatorsItem` first as fixed entry +- Filtered items by `ItemType` to separate folders from connections +- Implemented recursive nesting via `FolderItem.getChildren()` +- Root level shows both folders and connections where `parentId === undefined` + +**Pros:** +- ✅ Clear hierarchical structure +- ✅ Fixed LocalEmulators position preserved +- ✅ Efficient querying with ItemType discrimination +- ✅ Clean separation between root and nested items + +**Cons:** +- ⚠️ Folder/connection type determination needs refinement +- ⚠️ Currently queries both connection types separately + +--- + +### 4. ✅ Implement Drag-and-Drop Controller +**Commits:** cd1b61c +**Status:** FULLY COMPLETED + +**Actions Taken:** +- Created `ConnectionsDragAndDropController` implementing `TreeDragAndDropController` +- Implemented `handleDrag()` to capture draggable items +- Implemented `handleDrop()` with comprehensive validation: + - Multi-selection support + - Boundary crossing warnings (emulator vs non-emulator) + - Duplicate name detection + - Circular reference prevention + - Recursive folder content moving +- Registered controller in `ClustersExtension.ts` + +**Pros:** +- ✅ Intuitive drag-and-drop UX +- ✅ Comprehensive validation prevents data loss +- ✅ Boundary crossing detection protects against configuration errors +- ✅ Supports both moving individual items and entire folder trees +- ✅ Proper integration with VS Code drag-and-drop APIs + +**Cons:** +- ⚠️ Moving across connection types is slower (delete+recreate vs simple update) +- ⚠️ User must confirm boundary crossing for each item (could batch) +- ⚠️ Error handling could be more granular + +--- + +### 5. ✅ Add Clipboard State to Extension Variables +**Commits:** [Current] +**Status:** FULLY COMPLETED + +**Actions Taken:** +- Added `ClipboardState` interface to extensionVariables.ts +- Added `clipboardState` property to ext namespace +- Defined operation types: 'cut' | 'copy' +- Integrated context key management for menu enablement + +**Pros:** +- ✅ Clean typed interface +- ✅ Centralized state management +- ✅ Context key enables/disables paste command appropriately + +**Cons:** +- ⚠️ State persists only during extension lifecycle +- ⚠️ No cross-window clipboard support + +--- + +### 6. ✅ Add Folder CRUD Commands +**Commits:** bff7c9b, 41e4e10, 075ec64, [Current] +**Status:** FULLY COMPLETED + +**Actions Taken:** +- **createFolder**: Prompt-based folder creation with duplicate validation +- **renameFolder**: Rename with sibling name conflict checking +- **deleteFolder**: Recursive deletion with confirmation dialog +- **cutItems**: Cut items to clipboard with context key management +- **copyItems**: Copy items to clipboard with context key management +- **pasteItems**: Complex paste operation with: + - Duplicate name handling (prompts for new name) + - Support for both cut (move) and copy operations + - Recursive copying of folder hierarchies + - Boundary crossing support + - New ID generation for copies + - Connection type migration handling + +**Pros:** +- ✅ All commands follow wizard pattern for consistency +- ✅ Comprehensive validation at every step +- ✅ User prompts prevent data loss +- ✅ Paste operation handles all edge cases +- ✅ Recursive operations preserve folder structure +- ✅ Context-aware paste target determination + +**Cons:** +- ⚠️ Paste operation is complex and may have edge cases +- ⚠️ No undo functionality +- ⚠️ Cut items remain in clipboard if paste fails partway +- ⚠️ Connection type currently hardcoded in some places + +--- + +## Partially Completed Work Items + +### 7. ⚠️ Register View Header Commands +**Status:** PARTIALLY COMPLETED +**Priority:** HIGH + +**Completed:** +- Commands registered in package.json +- Basic infrastructure in place + +**Remaining:** +- Add navigation header buttons for createFolder +- Implement generic renameItem dispatcher +- Add context key `documentdb.canRenameSelection` +- Configure proper menu visibility + +**Pros of Current State:** +- ✅ Foundation is solid + +**Cons of Current State:** +- ⚠️ Commands not accessible from header buttons +- ⚠️ No generic rename command for both folders and connections + +--- + +### 8. ⚠️ Register Context Menu Commands +**Status:** PARTIALLY COMPLETED +**Priority:** HIGH + +**Completed:** +- Basic folder commands in context menu +- Command registration structure + +**Remaining:** +- Add cut/copy/paste to context menu +- Refine contextValue patterns +- Add "when": "never" to hide from command palette +- Configure when clauses for clipboard operations + +**Pros of Current State:** +- ✅ Core commands accessible + +**Cons of Current State:** +- ⚠️ Cut/copy/paste not in context menu yet +- ⚠️ Commands may appear in command palette unnecessarily + +--- + +## Not Started Work Items + +### 9. ⬜ Complete Extension Integration +**Status:** NOT STARTED +**Priority:** MEDIUM + +**Remaining Tasks:** +- Add onDidChangeSelection listener to connectionsTreeView +- Update documentdb.canRenameSelection context key based on selection +- Implement selection-based command enablement + +**Impact:** +- Context-aware command enablement would improve UX +- Selection tracking would enable more sophisticated features + +--- + +### 10. ⬜ Add Unit Tests +**Status:** NOT STARTED +**Priority:** MEDIUM-HIGH + +**Remaining Tasks:** +- Create folderOperations.test.ts +- Test all CRUD operations +- Test hierarchy operations (nesting, moving) +- Test edge cases (circular references, duplicates) +- Test boundary crossing +- Test clipboard operations +- Mock ConnectionStorageService + +**Impact:** +- Critical for ensuring reliability +- Would catch regressions +- Would document expected behavior + +--- + +## Overall Assessment + +### Implementation Quality + +**Strengths:** +1. **Unified Storage Architecture**: The hybrid approach with type discriminators is clean and maintainable +2. **Comprehensive Validation**: Duplicate names, circular references, and boundary crossing are all handled +3. **User Experience**: Prompts guide users through complex operations +4. **Extensibility**: Architecture supports future features (tags, metadata, etc.) +5. **Error Handling**: Most operations have proper error handling and user feedback + +**Areas for Improvement:** +1. **Testing**: No automated tests yet - critical gap +2. **UI Integration**: Header buttons and refined context menus needed +3. **Connection Type Handling**: Currently hardcoded in places, needs proper tracking +4. **Undo Support**: No way to undo accidental operations +5. **Performance**: Large folder hierarchies not yet tested + +--- + +### Completion Status + +**Overall Progress:** 80% complete + +**Functional Completeness:** +- ✅ Core storage layer: 100% +- ✅ Tree view rendering: 100% +- ✅ Drag-and-drop: 100% +- ✅ Clipboard operations: 100% +- ✅ Basic CRUD commands: 100% +- ⚠️ UI integration: 60% +- ⚠️ Context key management: 50% +- ❌ Unit tests: 0% + +**Production Readiness:** ~70% +- Ready for alpha testing with known gaps +- Needs tests before production release +- UI polish required +- Edge case testing needed + +--- + +## Recommended Next Steps + +### Priority 1 (Critical for Production): +1. Add comprehensive unit tests +2. Complete context menu integration +3. Add header button commands +4. Test with large datasets + +### Priority 2 (Important for UX): +1. Implement selection-based command enablement +2. Add undo/redo support or confirmation dialogs +3. Improve error messages +4. Add loading indicators for long operations + +### Priority 3 (Nice to Have): +1. Folder icons/colors customization +2. Folder metadata (description, tags) +3. Bulk operations +4. Folder templates + +--- + +## Technical Debt + +1. **Connection Type Tracking**: Currently defaults to Clusters, needs proper tracking per folder +2. **Error Recovery**: Partial paste failures leave inconsistent state +3. **Code Duplication**: Some logic duplicated between paste and drag-and-drop +4. **Migration Testing**: v2->v3 migration not tested with real data +5. **Performance**: No optimization for large hierarchies + +--- + +## Conclusion + +The folder hierarchy feature is ~80% complete with a solid foundation. The unified storage approach is working well and provides a clean architecture for future enhancements. The main gaps are in testing and UI polish. The implementation is functional and ready for alpha testing, but needs tests and refinement before production release. + +**Verdict:** Implementation follows the plan effectively and delivers the core functionality. Some planned items are incomplete but the foundation is strong enough to support completing them incrementally.
