-Drill 1.16 and later supports the ANALYZE TABLE statement. The ANALYZE TABLE
statement computes statistics on Parquet data stored in tables and directories.
ANALYZE TABLE writes statistics to a JSON file in the `.stats.drill` directory,
for example `/user/table1/.stats.drill/0_0.json`. The optimizer in Drill uses
these statistics to estimate filter, aggregation, and join cardinalities to
create more efficient query plans.

You can run the ANALYZE TABLE statement to calculate statistics for tables,
columns, and directories with Parquet data; however, Drill will not use the
statistics for query planning unless you enable the `planner.statistics.use`
option, as shown:
