STD.System.Thorlib.Group ( )

The Group function returns the name of the node group running the workunit. This name is used in ECL code to specify the target CLUSTER for an OUTPUT action or a PERSISTed attribute.

Deprecated in containerized environments. In containerized HPCC Systems deployments, compute nodes are ephemeral and the node group name has no stable meaning. Storage is decoupled from compute and is referenced via data planes (for example, 'data'). In containerized deployments this function returns a blank string (''), which is interpreted as the default data plane. New ECL code targeting containerized HPCC should use an explicit data plane name (for example, 'data') rather than calling this function.

Example:

IMPORT STD;
A := STD.System.Thorlib.Group();
