> 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. REFRESH TABLE
> METADATA COLUMNS NONE `/tmp/employee` will not store column metadata for any
> column.
> By default, if the optional 'COLUMNS' clause is omitted, column metadata is
> collected for all the columns.
