Abstract

A computer-implemented method for managing an index table associated with a data table includes obtaining an index entry associated with a key in the data table. The computer-implemented method further includes determining whether an index page associated with the index entry is in a buffer pool, wherein the buffer pool includes a plurality of index pages loaded from the index table and at least one temp index. The computer-implemented method further includes adding, in response to determining that the index page associated with the index entry is not in the buffer pool, the index entry into the at least one temp index. The computer-implemented method further includes consolidating the at least one temp index into the index table.
