Description
Adds TopK as a community vector database adapter.
{database_name}__)create_data_pointsstores the LSN returned by each upsert inself._lsnsin a dict, keyed by a collection name to keep read-your-own-writes consistency.What's included:
TopKAdapterimplementingVectorDBInterface(search, batch search,belongs_to_setnode filtering with
AND/OR, batched upserts under the API size limits, prefix-gated prune)TopKDatasetDatabaseHandlerfor per-dataset isolationfrom cognee_community_vector_adapter_topk import registerexample.py,tests/test_topk.py,README.mdCI (TODO)
I haven't wired the test into CI (
test_topk.yml+vector_db_community_tests.yml)because the test runs against the live TopK API. The repo needs to add the
TOPK_API_KEYsecret.TopK account as well as test project + API key needs to be provisioned at console.topk.io.
