Abstract

Techniques are described herein for using user-defined aggregate functions for updating inverted index tables. A user-defined aggregate function is registered in a database system for updating an index table based on changes stored in a staging table. A query specifying the user-defined aggregate function may be executed in parallel to parallelize the updating of the index table.
