There's a discussion about Deprecate DynamodbCatalog on [email protected]. Maybe we should join in?

Based on the discussion, it appears that few people utilize this catalog. Do you have a specific use case for it?

They suggest to use Glue. Let me figure out does it work for me. cc @Xuanwo

Thanks! Feel free to implement the DynamoDB catalog in iceberg-rust if you still want it.

I just wanted to update you on the current situation within the community: there is a disscusion to deprecate it. And it's highly possible for us to deprecate it too someday.

Update: We decide to use Postgres, cuz none of us know Glue😢. I will start working on the SQL Catalog which I think it may be more widely used.
I will close this PR and move this implementation to my personal repo.

I remember @JanKaul mentioned that he already has an implementation for this, maybe we can help to port it?

Yes, sorry I didn't have time to implement it. I'll try to work on it today.
