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 > -------------------------------------------- > > Key: DRILL-7058 > URL: https://issues.apache.org/jira/browse/DRILL-7058 > Project: Apache Drill > Issue Type: Sub-task > Components: Metadata > Reporter: Venkata Jyothsna Donapati > Assignee: Venkata Jyothsna Donapati > Priority: Major > Labels: doc-impacting > Fix For: 1.16.0 > > Original Estimate: 72h > Remaining Estimate: 72h > > 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.
