Venkata Jyothsna Donapati updated DRILL-7058:
---------------------------------------------
Description:
Modify the REFRESH TABLE METADATA command to specify selected columns which are
deemed interesting in some form - either sorted/partitioned/clustered by and
column metadata will be stored only for those columns. The proposed syntax is
REFRESH TABLE METADATA *_[ COLUMNS (list of columns) / NONE ]_* <table
path>
For example, REFRESH TABLE METADATA COLUMNS (age, salary) `/tmp/employee`
stores column metadata only for the age and salary columns.
By default, if the optional 'COLUMNS' clause is omitted, column metadata is
collected for all the columns.
> Refresh command to support subset of columns
