[I] [Improment] The issue of indexing large volumes of data tables. [incubator-paimon]

wg1026688210 opened a new issue, #2253:
URL: https://github.com/apache/incubator-paimon/issues/2253

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
   
   
   ### Motivation
   
   Now we have seen significant improvements in query performance through index creation. However, we have encountered several issues during the indexing process.
   1.  Some tasks before sorting and writing to Paimon are getting stuck waiting for data for a long time.
   2.  Due to data skewness, some indexing tasks take a long time to execute.
   3.  The flink batch Job of building index will global failover after taskManager oom
   4.  FilesTable can not query the parition which has built index
