Within the TDMaps system database, there are many SQL stored procedures for automating system expansion and map assignments. The procedures in TDMaps fall into two main categories: Advisor and Mover.
  • Advisor procedures analyze tables to recommend the best map for each table. The recommendations can optionally be customized and used as input for the Mover.
  • Mover procedures redistribute the data for a specified list of tables based on new maps. Mover can use multiple worker sessions to achieve the desired level of concurrency. One manager session schedules the execution of groups of related actions and coordinates the worker sessions.
