[GitHub] [incubator-paimon] newsuperchao opened a new issue, #1816: [Feature] Paimon dynamic bucket supports adding buckets based on storage size.

newsuperchao opened a new issue, #1816:
URL: https://github.com/apache/incubator-paimon/issues/1816

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
   
   
   ### Motivation
   
   The existing dynamic bucket solution is based on the data volume within each bucket to determine whether to add a new one. Due to the need to cache primary keys, when the table's data volume is large, more memory is required to support the dynamic bucket feature. It is hoped that the addition of buckets can be determined based on the storage size of the buckets, reducing the additional memory overhead.
   
   ### Solution
   
   By detecting whether the written bucket capacity reaches a threshold before adding new ones, it's also necessary to consider the scenario where the bucket capacity might decrease after bucket compaction.
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [ ] I'm willing to submit a PR!

   I am interested in this issue, where should I go to view the existing dynamic bucket solution。I don't have a good idea at the moment, but it feels very feasible。
