| ### Why Pixeltable as a Document Store? | ||
|
|
||
| | Feature | Pixeltable | Typical vector DBs | | ||
| |---------|-----------|-------------------| | ||
| | Persistent storage | Built-in (embedded PostgreSQL) | Varies | | ||
| | Computed columns | Native — auto-run transforms on insert | No | | ||
| | Version history | Built-in — time-travel queries | No | | ||
| | Multimodal types | Image, Video, Audio, Document | Text only | | ||
| | Metadata filtering | JSON + SQL predicates | Limited | | ||
| | Embedding auto-compute | Via computed columns | Manual | | ||
|
|
||
| The `.table` escape hatch lets you break out of the Haystack interface to use the full Pixeltable API — add computed columns, run LLM inference on insert, query version history, and work with multimodal data. |

I have doubts regarding including that section. It sounds a bit too overpromotional. We avoid comparing integrations with each other, or doing any sort of benchmarks. This listing is supposed to present the options available.

Do you think we could also add a logo of Pixeltable, similarly to the other integrations?

Summary
Adds a community integration page for haystack-pixeltable — a Haystack Document Store and Retriever backed by Pixeltable.
PyPI: https://pypi.org/project/haystack-pixeltable/
Repo: https://github.com/pixeltable/haystack-pixeltable
Components
PixeltableDocumentStore— full HaystackDocumentStoreprotocol (write, delete, filter, count, serialization)PixeltableRetriever— vector similarity search with top-k and metadata filteringWhat makes this integration different
Pixeltable is open-source multimodal data infrastructure. Unlike standalone vector databases, it provides:
Image,Video,Audio,Documentcolumn types alongside text and embeddings.tableescape hatch — break out of the Haystack interface to use Pixeltable's full API (add computed columns, query versions, multimodal operations)Checklist
