Hi @lutengda, can you tell us more? We support S3, GCS and Azure compatible backends. You'd like support for one not in the list?

[lutengda]

Yes, I would like to support a traditional relational database or a time series database as the storage backend, which would provide more flexibility in the choice of storage backend and provide better scalability and high availability

[lutengda]

I think tempo is a great monitoring solution, and more people will choose to use it if they can support custom storage backends

[mapno]

Tempo is built around object storage and uses a column-oriented format (Apache Parquet) to store and read traces. How do you see a relational database improving or extending Tempo? That's a massive change on how Tempo operates.

or a time series database

Tempo stores traces, not time series. I'm not sure I understand what you mean by that.

if they can support custom storage backends

Also, I don't think I understand what you mean by custom storage backend.

What I'd see more realistic is adding support for a object storage solution that's not S3, GCS or Azure blob storage. Is there one you'd like to see support for?

Ok, I see, maybe my idea is not too mature, thank you for your answer
