ChromaDB

ChromaDB is a vector database used for similarity searches on embeddings. It’s extremely easy to use if you are using Python and works well with LangChain.

• Turn off Chroma Telemetry in Langchain

  You can turn off sending telemetry data to ChromaDB (now a venture backed startup) when using langchain.

• Langchain Self Query With Dates

  Self querying by date using LangChain doesn’t work well. The default schema used for parsing natural language into the internal representation of langchain for querying a vector store does not work with dates because it uses the wrong type (it tries to use a dict but you can only filter using integers or strings).

• Emacs and Chromadb

  The nice part about ChromaDB is that you can read the tables in SQLite using the new Emacs 29 sqlite-mode. That means there is no other configuration for accessing the database, you can open the sqlite file directly.
