### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description 当前colocate的限制： 1. 多租户部署时副本冗余：例如租户A需要JOIN租户B的表，租户C需要JOIN租户B的表，但是租户A不需要JOIN租户C的表，理论上我们只需要在租户A/C的机器上增加租户B的表的副本，租户A/C就可以在自己的机器上做ColocateJoin，但是当前的Colocate实现要求租户A/B/C的表必须在A/B/C三个租户的机器上都放置副本，导致副本冗余。 2. 分桶数限制：当前colocate的实现要求两个表的分桶数必须相同才能做ColocateJoin，当JOIN的表的数量级差别比较大时，难以设置统一的分桶数。 方案： 1. 支持租户粒度的colcoate，避免副本冗余问题。同时，单个租户的colocate失效不影响其他租户。 2. 支持分桶数为倍数关系的colocate ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
