Light weight index for querying low-frequency data in a big data environment

Abstract:

The present disclosure relates to searching for and committing low-frequency data to a database. An example method generally includes receiving, from a requesting application, a query for data from the data repository. A database system retrieves a set of indices associated with the data specified in the query from an index table in the data repository. Upon determining that the set of indices comprises a non-null set, the database system retrieves records associated with each index in the set of indices from a data table associated with the index table and returns the retrieved records to the requesting application.
