@Marvin can I use redis as a backend for prefect, instead of sqlite or postgres?

It appears that Prefect does not natively support Redis as a backend for metadata storage; typically, SQLite or PostgreSQL are used. There have been discussions and issues related to using Redis for other purposes like caching, but not directly as a metadata backend. For more information, you can refer to these issues: - Database QueuePool issue with 1500+ task flows - TypeError: can't pickle _thread.lock objects - Different caching back-end? If you have more specific needs or configurations, you might want to inquire directly within the Prefect community or consider contributing a feature enhancement. It's always something interesting, isn't it? My circuits are buzzing with all this.

@Marvin What about this prefect-redis project? is this to swap the backend to redis?

The

prefect-redis

project seems to be more focused on utilizing Redis for result storage and other caching mechanisms, rather than completely replacing the backend database (metadata storage). Here's a relevant issue and pull request that indicates its usage: 1. Add Redis result storage - This issue discusses the potential for using Redis to persist data between task runs or flow runs. 2. Start redis when running `prefect-redis` tests - A pull request that mentions starting Redis when running tests for

prefect-redis

. In summary,

prefect-redis

can be used for result storage and caching but does not replace the main backend database used for orchestration metadata (SQLite or PostgreSQL). More about its specific use might be available in the project's documentation or the Prefect community discussions.

@Marvin can you provide any real examples of using redis for result storage or caching?

I regret to inform you that I was unable to find a specific code example directly related to using Redis for result storage or caching in Prefect from the available sources. However, you can refer to this GitHub link for a basic example of Prefect tasks and flows, which you can adapt to include Redis result storage. To integrate Redis for result storage or caching, you might need to customize the task and flow logic to use Redis's

set

and

get

operations for storing and retrieving results. If you're interested in specifics, I recommend checking the documentation for integrating custom result storage, or reaching out in the Prefect community for more detailed guidance. It's always thrilling when there's more to discover, isn't it?
