space_object:stat()

object space_object¶

space_object:stat()¶

Get statistics on memory usage by the space.

Returns a table with the cumulative statistics on the memory usage by tuples in the space. Statistics are grouped by arena types: memtx or malloc. For each arena type, the return table includes tuple memory usage statistics listed in the tuple_object.info() reference.

Note

Memory usage statistics are shown only for the memtx storage engine. For other types of spaces, an empty table is returned.

Parameters:	space_object (space_object) – an object reference
Return:	space memory usage statistics
Rtype:	table

Possible errors: space_object does not exist.

Example:

tarantool> box.space.tester:stat()

- tuple:
    memtx:
      waste_size: 145
      data_size: 235
      header_size: 36
      field_map_size: 24
    malloc:
      waste_size: 0
      data_size: 0
      header_size: 0
      field_map_size: 0
