  • Synthesized predicate driven index selection for partitioned table
    Patent number: 11741079
    Abstract: A system and method for receiving a query of a partitioned table, the query including a first index predicate associated with a first partition key column; determining that one or more of the query is missing a second index predicate and the first index predicate is unusable for index probing; responsive to determining that one or more of the query is missing the second index predicate and the first index predicate is unusable for index probing, generating one or more synthesized predicates used to process the query using an index scan.
