<!-- Please specify the module before the PR name: [core] ... or [flink] ... --> ### Purpose <!-- Linking this pull request to the issue --> Linked issue: close #xxx In Paimon's system table $branches, when a user needs to query specific branch information, the previous implementation did not support pushing down the filtering criteria of branch_name. This means that even if we only want to query one or a few specific branches, Paimon will read all branch information and then filter it at the computation engine layer This change aims to optimize the query performance of the $branches table by implementing the pushdown of filtering conditions for the branch_name field, allowing queries to be filtered directly at the storage layer based on the branch name, thereby significantly improving query efficiency. <!-- What is the purpose of the change --> ### Tests <!-- List UT and IT cases to verify this change --> org.apache.paimon.flink.BranchSqlITCase##testBranchesTableFilter with adding more case for the method. ### API and Format <!-- Does this change affect API or storage format --> ### Documentation <!-- Does this change introduce a new feature --> -- This is an automated message from the Apache Git Service.
