For the  used_pages  and  total_pages  columns, resources are measured in pages, which are 32K in size for  DataMemory  and 8K for  IndexMemory . For long message buffer memory, the page size is 256 bytes. The  memory_per_fragment  table provides information about the usage of memory by individual fragments. The  memory_per_fragment  table contains the following columns: Name of this fragment Name of this fragment’s parent Type of object; see text for possible values Table ID for this table Node ID for this node Kernel block instance ID Fragment ID (number) Number of bytes allocated for fixed-sized elements Free bytes remaining in pages allocated to fixed-size elements Length of each fixed-size element in bytes 4564 • fixed_elem_size_bytes • fixed_elem_free_bytes • fixed_elem_alloc_bytes • fragment_num • block_instance • node_id • table_id • type • parent_fq_name • fq_name 23.5.14.37 The ndbinfo memory_per_fragment Table
