PRIORITIZATION OF DATA FROM IN-MEMORY DATABASES

摘要

Column accesses to columns of one or more database tables may be determined based on database queries accessing the one or more database tables. Row accesses to rows of the one or more database tables may be determined based on the queries. A priority may be assigned to a column of a row from the one or more database tables based on the determined column accesses of the column and the row accesses of the row. The column of the row may be moved from random access memory to hard disk based on the assigned priority.

1. A computer-implemented method comprising:
determining, by a computer processor, column accesses to columns of at least one database table based on database queries accessing the at least one database table; determining row accesses to rows of the at least one database table based on the queries; assigning a priority to a column of a row from the at least one database table based on the determined column accesses of the column and the row accesses of the row; and moving the column of the row from random access memory to hard disk based on the assigned priority.
