Abstract
Trigger-free asynchronous maintenance of custom indexes and skinny performance meta-structures is described. A database system receives a request to manipulate data in an object in a database table, and determines whether the object in the database table is associated with a user-based data structure. If the object in the database table is associated with the user-based data structure, the database system manipulates the data in the object in the database table and data in an object in an intermediate data table. The database system receives a query, and determines whether the query requests any data that is in the user-based data structure. If the query requests any data that is in the user-based data structure, the database system creates a query result by combining any data that is in the object in the intermediate data table with any requested data that is in the user-based data structure, and outputs the query result.
