restartable
- type:
- boolean
- example:
- config restartable : true;
- description:
- The operator instance can be restarted, for example after a user-requested stopPE completes or after a partition crashes due to a runtime error. The restartable config is implied by the relocatable config. Furthermore, if an operator A is restartable and operator B is not, then A and B are partition-exlocated (cannot be in the same partition), unless the compiler option -O, --setRelaxFusionRelocatabilityRestartability is used. Remember from the language specification that a local config overrides a global config; similarly, a local inferred config overrides a global config even if that global config is explicit.
- default:
- true
- where:
- Any operator invocation or composite
operator. Tip: You can set config restartable on a main composite to make all enclosed PEs restartable.
