Description
Right now you can run COMPUTE STATS for Kudu tables to compute table/column stats, but it doesn't support stats for partitions/tablets. With such statistics we could consider other planner improvements.
The 'show table stats' command shows the lack of tablet statistics, though this isn't useful:
> compute stats foo; > show table stats foo; +--------+-----------+----------+-----------------------------------------+------------+ | # Rows | Start Key | Stop Key | Leader Replica | # Replicas | +--------+-----------+----------+-----------------------------------------+------------+ | -1 | | 00000001 | foo1.example.com:7050 | 1 | | -1 | 00000001 | 00000002 | foo2.example.com.net:7050 | 1 | | -1 | 00000002 | 00000003 | foo3.example.com:7050 | 1 |
