wjhypo opened a new issue #9809:
URL: https://github.com/apache/druid/issues/9809


   ### Motivation
   Currently segment pruning only uses the time interval. For further filtering 
on secondary partitions, only single dimension ShardSpec is supported (done in 
#2982). For hash based partitioning, we can also apply pruning by rehash the 
filtered partitioning dimensions in the query  to locate segments.
