definitions in Greenplum 7. About Partition Pruning Partition pruning is a query optimization technique that improves performance for declaratively partitioned tables. You can enable or disable partition measurement_usls_idx ATTACH PARTITION measurement_usls_202102_idx; ... You can use this technique with UNIQUE and PRIMARY KEY constraints too; the indexes are created implicitly when the constraint search order by making the outer query ORDER BY a “path” column constructed in this way. A helpful technique for testing a query when you are not certain if it might loop indefinitely is to place a LIMIT in

search order by making the outer query ORDER BY a path column constructed in this way. A helpful technique for testing a query when you are not certain if it might loop indefinitely is to place a LIMIT LIMIT 100; The technique works because the recursive WITH implementation evaluates only as many rows of a WITH query as are actually fetched by the parent query. Using this technique in production is is not recommended, because other systems might work differently. Also, the technique might not work if the outer query sorts the recursive WITH results or join the results to another table. Data-Modifying
