------------------------------------------
Summary: Provide consistent information about partitioned Iceberg
tables
Key: IMPALA-11538
URL: https://issues.apache.org/jira/browse/IMPALA-11538
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Zoltán Borók-Nagy
In HMS we don’t store information about Iceberg partitions, we let Iceberg
handle them.
In Impala CatalogD/FE/BE we usually treat Iceberg tables as non-partitioned
tables, and only care about Iceberg partitions when really needed, e.g. INSERTs
need to be partition-aware, DPP for identity-partitioned tables, also SHOW
PARTITIONS must show information about the actual Iceberg partitions, etc.
But in some cases the users see inconsistent information because the
non-partitioned nature is revealed in some cases. We need to work on this to
not confuse users.
Some places that shows partitioned Iceberg tables as non-partiotioned:
* EXPLAIN statements
* SHOW TABLE STATS
