    • 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.
    • 系统包括生成包括表的分区列和阈值大小的表的定义,用于表的第一存储器分区的分配,确定第一存储器分区中的表的记录的大小大于 阈值大小,并且响应于第一存储器分区中的表的记录的大小大于阈值大小的确定,确定在第一存储器分区中的表的记录中的分区列的最大值 存储器分区,确定第一存储器分区中的表的记录中的分区列的最小值,生成表示分区列的值在其中包括最小值的范围内的表的记录的元数据 值和最大值存储在第一个内存分区中,并为表分配第二个内存分区。
