Thank you for contributing to LangChain!

• PR title: "package: description"

  • Where "package" is whichever of langchain, community, core, etc. is being modified. Use "docs: ..." for purely docs changes, "infra: ..." for CI changes.
  • Example: "community: add foobar LLM"
    community: langchain_community/vectorstore/oraclevs.py

• PR message: Delete this entire checklist and replace with

  • Description: Refactored code to allow a connection or a connection pool.
  • Issue: Normally an idel connection is terminated by the server side listener at timeout. A user thus has to re-instantiate the vector store. The timeout in case of connection is not configurable. The solution is to use a connection pool where a user can specify a user defined timeout and the connections are managed by the pool.
  • Dependencies: None
  • Twitter handle:

• Add tests and docs: This is not a new integration. A user can pass either a connection or a connection pool. The determination of what is passed is made at run time. Everything should work as before.

• Lint and test: Already done.

Additional guidelines:

• Make sure optional dependencies are imported within a function.
• Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests.
• Most PRs should not touch more than one package.
• Changes should be backwards compatible.
• If you are adding something to community, do not re-import it in langchain.

@baskaryan, @efriis, @rohanaggarwal7997 - As per our last interaction I have split my old transaction into two. This transaction offers support for the database connection pool. In doing so, I have renamed the variable connection to client and set its datatype to Any. This has resulted in the refactoring of the code. It is not complicated, but occurs everywhere connection was used. Please review.
