This PR rolls out part of the new proposed interface for vectorstores (https://github.com/langchain-ai/langchain/pull/23544) to existing store implementations. The PR makes the following changes: 1. Adds standard upsert, streaming_upsert, aupsert, astreaming_upsert methods to the vectorstore. 2. Updates `add_texts` and `aadd_texts` to be non required with a default implementation that delegates to `upsert` and `aupsert` if those have been implemented. The original `add_texts` and `aadd_texts` methods are problematic as they spread object specific information across document and **kwargs. (e.g., ids are not a part of the document) 3. Adds a default implementation to `add_documents` and `aadd_documents` that delegates to `upsert` and `aupsert` respectively. 4. Adds standard unit tests to verify that a given vectorstore implements a correct read/write API. A downside of this implementation is that it creates `upsert` with a very similar signature to `add_documents`. The reason for introducing `upsert` is to: * Remove any ambiguities about what information is allowed in `kwargs`. Specifically kwargs should only be used for information common to all indexed data. (e.g., indexing timeout). *Allow inheriting from an anticipated generalized interface for indexing that will allow indexing `BaseMedia` (i.e., allow making a vectorstore for images/audio etc.) `add_documents` can be deprecated in the future in favor of `upsert` to make sure that users have a single correct way of indexing content. --------- Co-authored-by: ccurme <chester.curme@gmail.com> |
