DML Commands

In IQ 15.0, global transactions can be run from the coordinator and any write server. DML commands that modify tables in the shared IQ store are global DML commands. Any transaction that contains a global DML command becomes a global transaction.

• Global DML Commands
  Global DML commands behave as if they were executed on the coordinator, and obey the same locking rules as on a single server.
• Table Data Scope
  When running DML commands in multiplex, the visibility of the table rows differs for different table types.
• Tables in Join Indexes
  Some restrictions apply to tables in join indexes.
