摘要： In a particular embodiment, a method includes storing, at a staging table of a database, a data update generated based on a transaction performed with respect to a data table that is associated with one or more indexes. Each index of the one or more indexes is maintained externally to the database. The method further includes maintaining the data update at the staging table at least until index update data is received at the database. The index update data represents a modification, based on the data update, to a particular index of the one or more the indexes.

摘要： 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.
