Abstract

A system includes generation of a definition of a table including a partitioning column of the table and a threshold size, allocation of a first memory partition for the table, determination that a size of the records of the table in the first memory partition is greater than the threshold size, and, in response to the determination that the size of the records of the table in the first memory partition is greater than the threshold size, determination that a maximum value of the partitioning column in the records of the table in the first memory partition, determination of a minimum value of the partitioning column in the records of the table in the first memory partition, generation of metadata indicating that records of the table in which the value of the partitioning column is in a range between and including the minimum value and the maximum value are stored in the first memory partition, and allocation of a second memory partition for the table.
