Teradata Database 16.10 and later provides a map architecture in which every table uses a map that specifies the AMPs on which the table rows are stored.

Teradata Database uses two types of maps:
  • Contiguous maps include all AMPs within a specified range. Teradata Database creates contiguous maps during a system initialization or reconfiguration.
  • Sparse maps include a subset of AMPs from a contiguous map. Teradata Database provides two sparse maps you can use, and you can also create new sparse maps if you have appropriate database privileges.
