Add SQL Conversation Storage

[Rajaniraiyn]

Issue number: #110

Summary

Changes

This PR adds a new feature, SQL Storage, to the Multi-Agent Orchestrator system. It introduces persistent conversation storage using the libsql library, supporting both local SQLite databases and remote databases. This implementation improves flexibility, reliability, and scalability for storing agent conversation history.

User experience

Before this change:

• Conversation data was limited to DynamoDB or in-memory storage without a CustomStorage implementation.

After this change:

• Users can store conversations persistently with support for both local and remote databases.
• Provides robust solutions for edge and serverless deployments.
• Simplifies setup with automatic schema creation and indexing.

Any update on this PR?

I've got a similar use-case where we're using a SQL DB for storing conversations.
I've rolled my own storage engine for this outside of the multi-agent orchestrator framework, but having this built-in would be pretty nice.

Looks like the current HEAD of this fork needs a rebase. Happy to contribute if OP no longer has the bandwidth, but also not sure if the maintainers are willing to accept this. Looking for some feedback either way.

Thanks!

Hi @Rajaniraiyn,
Thanks for the PR.
We did some changes to the python version so that a user will install only the required libraries, not all of them.
Can you make changes so that it works for libsql similar to aws, anthropic and openai?
Check the setup.cfg and the init files.
The point is that we should install this lib only if we use this storage.

Also add a mention to this package in the doc for python.

Thanks.

Hey @cornelcroi
I have made the requested changes,

• made libsql installing when only used in python
• mention sql storage in overview docs

Thanks

[cornelcroi]

Can you add the pip install with the package like we did here ?
The users are more likely to skip the initial installation step so if they head to this storage, the installation of the lib must be recalled.

Thanks.

@cornelcroi I have updated both DynamoDB and SQL storage docs for python, specifying extras dependency installation. Let me know any further changes required.
Thanks.

Great, thanks.
Merging.

I am getting this error while using the SqlChatStorage with local db file

I am setting up the orchestrator in the fast api async method same as in fastapi streaming example

@fryz can you have a look?

Would be happy to contribute but I'm more familiar with the Typescript side of things.
Looks like it's because the query invoking the read from the DB is async and not being handled correctly? (eg: await?)

@fryz Yes, async method not awaited....full trace below

@psqbt Fixed Python async/sync inconsistencies and implemented a missing newly added method: #201

Thanks @Rajaniraiyn !
