| <indexterm audience="hidden">Hudi support in Impala</indexterm> Impala supports Read Optimized |
| Queries on Hudi tables as an experimental feature. Read Optimized Queries treat the latest |
| table snapshot as the commit or compaction action, expose only base/columnar files in latest |
| file slices, and guarantee the same columnar query performance as a non-Hudi columnar |
| table.</p> |
