Stefano Lottini	40e836c67e	added Cassandra caches to the llm_caching notebook doc (#10889 ) This adds a section on usage of `CassandraCache` and `CassandraSemanticCache` to the doc notebook about caching LLMs, as suggested in [this comment](https://github.com/langchain-ai/langchain/pull/9772/#issuecomment-1710544100) on a previous merged PR. I also spotted what looks like a mismatch between different executions and propose a fix (line 98). Being the result of several runs, the cell execution numbers are scrambled somewhat, so I volunteer to refine this PR by (manually) re-numbering the cells to restore the appearance of a single, smooth running (for the sake of orderly execution :)	12 months ago

Matvey Arye	6e02c45ca4	Add integration for Timescale Vector(Postgres) (#10650 ) Description: This commit adds a vector store for the Postgres-based vector database (`TimescaleVector`). Timescale Vector(https://www.timescale.com/ai) is PostgreSQL++ for AI applications. It enables you to efficiently store and query billions of vector embeddings in `PostgreSQL`: - Enhances `pgvector` with faster and more accurate similarity search on 1B+ vectors via DiskANN inspired indexing algorithm. - Enables fast time-based vector search via automatic time-based partitioning and indexing. - Provides a familiar SQL interface for querying vector embeddings and relational data. Timescale Vector scales with you from POC to production: - Simplifies operations by enabling you to store relational metadata, vector embeddings, and time-series data in a single database. - Benefits from rock-solid PostgreSQL foundation with enterprise-grade feature liked streaming backups and replication, high-availability and row-level security. - Enables a worry-free experience with enterprise-grade security and compliance. Timescale Vector is available on Timescale, the cloud PostgreSQL platform. (There is no self-hosted version at this time.) LangChain users get a 90-day free trial for Timescale Vector. --------- Co-authored-by: Bagatur <baskaryan@gmail.com> Co-authored-by: Avthar Sewrathan <avthar@timescale.com>	12 months ago

This can be solved setting `chunk_size=16`. However, I'd love to have this automated, not to force the user to figure where the issue comes from and how to solve it.

Ziyang Liu	931b292126	Add support for HTTP PUT in the open api agent prompt (#10763 ) Description: This PR adds HTTP PUT support for the langchain openapi agent toolkit by leveraging existing structure and HTTP put request wrapper. The PUT method is almost identical to HTTP POST but should be idempotent and therefore tighter than POST which is not idempotent. Some APIs may consider to use PUT instead of POST which is unfortunately not supported with the current toolkit yet.	12 months ago
