class AstraDBVectorStore(VectorStore):
"""Wrapper around DataStax Astra DB for vector-store workloads.
For quickstart and details, visit:
docs.datastax.com/en/astra/home/astra.html
Example:
.. code-block:: python
from langchain_astradb.vectorstores import AstraDBVectorStore
from langchain_openai.embeddings import OpenAIEmbeddings
embeddings = OpenAIEmbeddings()
vectorstore = AstraDBVectorStore(
embedding=embeddings,
collection_name="my_store",
token="AstraCS:...",
api_endpoint="https://<DB-ID>-<REGION>.apps.astra.datastax.com"
)
vectorstore.add_texts(["Giraffes", "All good here"])
results = vectorstore.similarity_search("Everything's ok", k=1)
Constructor Args (only keyword-arguments accepted):
embedding (Embeddings): embedding function to use.
collection_name (str): name of the Astra DB collection to create/use.
token (Optional[str]): API token for Astra DB usage.
api_endpoint (Optional[str]): full URL to the API endpoint,
such as "https://<DB-ID>-us-east1.apps.astra.datastax.com".
astra_db_client (Optional[astrapy.db.AstraDB]):
*alternative to token+api_endpoint*,
you can pass an already-created 'astrapy.db.AstraDB' instance.
async_astra_db_client (Optional[astrapy.db.AsyncAstraDB]):
same as `astra_db_client`, but the basis for the async API
of the vector store.
namespace (Optional[str]): namespace (aka keyspace) where the
collection is created. Defaults to the database's "default namespace".
metric (Optional[str]): similarity function to use out of those
available in Astra DB. If left out, it will use Astra DB API's
defaults (i.e. "cosine" - but, for performance reasons,
"dot_product" is suggested if embeddings are normalized to one).
Advanced arguments (coming with sensible defaults):
batch_size (Optional[int]): Size of batches for bulk insertions.
bulk_insert_batch_concurrency (Optional[int]): Number of threads
to insert batches concurrently.
bulk_insert_overwrite_concurrency (Optional[int]): Number of
threads in a batch to insert pre-existing entries.
bulk_delete_concurrency (Optional[int]): Number of threads
(for deleting multiple rows concurrently).
pre_delete_collection (Optional[bool]): whether to delete the collection
before creating it. If False and the collection already exists,
the collection will be used as is.
A note on concurrency: as a rule of thumb, on a typical client machine
it is suggested to keep the quantity
bulk_insert_batch_concurrency * bulk_insert_overwrite_concurrency
much below 1000 to avoid exhausting the client multithreading/networking
resources. The hardcoded defaults are somewhat conservative to meet
most machines' specs, but a sensible choice to test may be:
bulk_insert_batch_concurrency = 80
bulk_insert_overwrite_concurrency = 10
A bit of experimentation is required to nail the best results here,
depending on both the machine/network specs and the expected workload
(specifically, how often a write is an update of an existing id).
Remember you can pass concurrency settings to individual calls to
add_texts and add_documents as well.
A note on passing astra_db_client and/or async_astra_db_client instead
of the credentials (token, api_endpoint):
- if you pass only the async client when creating the store,
the sync methods will error when called.
- conversely, if you pass only the sync client, the async methods will
still be available, but will be wrapping its sync counterpart
in a `run_in_executor` construct instead of using the native async.
