The TDMaps database stores metadata for moving tables on to new maps. It contains procedures that perform automation tasks related to system expansion.

In addition to the AdjustSpace procedure, the database uses two other types, Advisor and Mover procedures. Advisor procedures analyze user tables within logged query plans and make recommendations for moving sets of tables onto maps. The output recommendations can be customized and input to the Mover, which moves data for a list of tables onto new maps.
