hudi-bot opened a new issue, #15051:
URL: https://github.com/apache/hudi/issues/15051

   In query processing, we need to scan many data blocks in HUDI table. 
However, most of them may not match the query predicate even after using column 
statistic info in the metadata table, row group level or page level statistics 
in parquet files, etc.
   
   The total data size of touched blocks determines the query speed, and how to 
save IO has become the key point to improving query performance. To address 
this problem, we introduce secondary index to improve hudi query performance.
   
   In the initial implementation, secondary index based on lucene will be 
carried out.
