… `PublishVersionTask.partitionVersionInfos` (#44846) ### What problem does this PR solve? Problem Summary: When FE handles BEs' tablet report and finds that there exists some expired txns on BE, it will generate publish version task. `TPartitionVersionInfo` with same values may be added to `transactionsToPublish` under same txn id many times when partitions involved in this failed txn involves many tablets on this BE. Because it uses `ArrayListMultimap`, these duplicate values may occupy a lot of memories when the number of tablets is large. ### Release note Fixed the issue of FE's memory occupation growing too fast in cases of persistent load and clone failures on merge-on-write tables. 修复了在merge-on-write表上有持续的导入失败和clone失败的情况下,FE使用内存增长过快的问题。
