Abstract

Managing database operations is provided. The method comprises receiving an insert statement for a database and determining if the insert statement is for a batch insert operation or random insert operation. For a batch insert operation, responsive to determining a threshold number of specified leaf pages are missing from a memory buffer pool of the database, the database asynchronously pre-loads missing leaf pages from a corresponding index on disk into the memory buffer pool. For a random insert operation, responsive to determining a threshold number of specified leaf pages are missing from a memory buffer pool of the database, the database builds at least one memory cache index and inserts key values specified in the insert statement in the memory cache index. The memory cache index is merged with a corresponding index on disk.
