----------------------------------------
Summary: Support missing types with theta sketches
Key: IMPALA-15106
URL: https://issues.apache.org/jira/browse/IMPALA-15106
Project: IMPALA
Issue Type: New Feature
Components: Backend
Reporter: Csaba Ringhofer
Existing theta sketches functions don't work for all types, for example there
is no support for TIMESTAMP. To use Iceberg's puffin files to store incremental
NDV stats, we need to support all types currently handled by COMPUTE STATS. The
Iceberg spec defines clearly how to do this for all types.
Note that we may be unable to use nanosecond timestamps, probably an error
could be returned in that case.
