InnoDB System Variables Enables the NUMA interleave memory policy for allocation of the  InnoDB  buffer pool. When innodb_numa_interleave  is enabled, the NUMA memory policy is set to  MPOL_INTERLEAVE  for the  mysqld  process. After the  InnoDB  buffer pool is allocated, the NUMA memory policy is set back to MPOL_DEFAULT . For the  innodb_numa_interleave  option to be available, MySQL must be compiled on a NUMA-enabled Linux system. CMake  sets the default  WITH_NUMA  value based on whether the current platform has  NUMA  support. For more information, see Section 2.9.7, “MySQL Source-Configuration Options” . Specifies the approximate percentage of the  InnoDB  buffer pool used for the old block sublist. The range of values is 5 to 95. The default value is 37 (that is, 3/8 of the pool). Often used in combination with  innodb_old_blocks_time . For more information, see Section 15.8.3.3, “Making the Buffer Pool Scan Resistant” . For information about buffer pool management, the LRU algorithm, and eviction policies, see Section 15.5.1, “Buffer Pool” . 3268 • innodb_old_blocks_time • innodb_old_blocks_pct Default Value OFF Command-Line Format --innodb-old-blocks-pct=# System Variable innodb_old_blocks_pct Scope Global Dynamic Yes SET_VAR  Hint Applies No Type Integer Default Value 37 Minimum Value 5 Maximum Value 95 Command-Line Format --innodb-old-blocks-time=# System Variable innodb_old_blocks_time Scope Global Dynamic Yes SET_VAR  Hint Applies No Type Integer Default Value 1000 Minimum Value 0
