6.16.37 The ndbinfo hash_maps Table

  • id

    The hash map's unique ID

  • version

    Hash map version (integer)

  • state

    Hash map state; see Object::State for values and descriptions.

  • fq_name

    The hash map's fully qualified name

The hash_maps table is actually a view consisting of the four columns having the same names of the dict_obj_info table, as shown here:

CREATE VIEW hash_maps AS
  SELECT id, version, state, fq_name
  FROM dict_obj_info
  WHERE type=24;  # Hash map; defined in dict_obj_types

See the description of dict_obj_info for more information.

The hash_maps table was added in NDB 8.0.29.
