Add support for additional Memory Bank services: DatabaseMemoryService/RedisMemoryService

[metalshanked]

Hi.
Currently only InMemoryMemoryService and VertexAiMemoryBankService are available.

Would be great to have a "DatabaseMemoryService" or "RedisMemoryService" for local / non cloud scaling.

Thanks!

Would be great to be able to use redis here.

Hello, are there any updates on this topic?

I'm surprised this issue hasn't gained more visibility. Given the ADK's premise of supporting any cloud and any model (not just GCP and Gemini), this flexibility should also extend to memory. We already have the DatabaseSessionService, so it seems logical to have a DatabaseMemoryService that supports a self-managed database. I believe this is a critical feature for the community.

For example, to summarize a session and add it to long-term memory without a hard dependency on Vertex. As it stands, I would have to implement this manually.

What is the community's current approach for using memory outside of Vertex? How would you suggest I proceed with this?

We are working on sqlite memory service.

Feel free to contribute other types of memory services.

We just added OpenMemory support in our community repo: google/adk-python-community#20
