<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>
