ctdbSetTablePartitionNumberBits

Set the number of bits used to store the raw partition number.

Declaration

CTDBRET ctdbDECL ctdbSetTablePartitionNumberBits(CTHANDLE Handle, UCOUNT bitno)

Description

Sets the number of bits used to store the raw partition number.

By default, 16 bits of the 64-bit record offset are used to reference the raw partition number, allowing each partitioned file to support up to 65535 member files over its lifetime. This function allows adjusting this when it is called before creating the file.

A value of 0 defaults to 16 bits, values less than 4 bits default to 4 bits (maximum 15 member files), and 32 bits is the maximum value.

Parameters

  • Handle [IN] - Table handle
  • bitno [IN] - Number of bits to be used for raw partition number
