HIVE-21078: Replicate column and table level statistics for unpartitioned
Hive tables
The column statistics is included as part of the Table object during
bootstrap dump and loaded when
corresponding table is created on replica.
During incremental dump and load, UpdateTableColStats event is used to
replicate the statistics.
In both the cases, the statistics is replicated only when the data is
replicated.
