Zusammenfassung:Systems, methods, and computer program products to persist external index data in a database are disclosed. In an embodiment, a method includes maintaining a database including a first data table that is configured to store data in a database format and a second data table that is configured to store index data. The index data represents an index of a first portion of the first data table, and the index maintained externally to the database by an index manager. The method also includes generating a data update representing a modification to the first data table and communicating the data update to the index manager. The method further includes receiving index update data from the index manager representing a modification to the index as a result of the data update and applying the index update data to the second data table.
