moveHotDataToColdVolume

Syntax

moveHotDataToColdVolume([checkRange=240])

Parameters

checkRange is an integer indicating the time range (in hours). The default value is 240, i.e., 10 days. If the parameter is specified, data within the range of [current time-hoursToColdVolumes-checkRange, current time-hoursToColdVolumes) will be migrated to coldVolumes.

Note:

For databases whose partitioning scheme includes the MONTH type, the default value is 10 calendar months. If a number of hours greater than 10 calendar months (24 * 31 * 10) is specified, it will be calculated according to that specified value.

Details

Migrate the specified data to coldVolumes.

The migration policy of moveHotDataToColdVolume is different from setRetentionPolicy. See Tiered Storage for more information.
