public static final class CreateProcRequest.ExecutionMode
extends Object

The execution mode of the proc. Supported values:

• DISTRIBUTED: Input table data will be divided into data segments that are distributed across all nodes in the cluster, and the proc command will be invoked once per data segment in parallel. Output table data from each invocation will be saved to the same node as the corresponding input data.
• NONDISTRIBUTED: The proc command will be invoked only once per execution, and will not have direct access to any tables named as input or output table parameters in the call to GPUdb.executeProc(ExecuteProcRequest). It will, however, be able to access the database using native API calls.

The default value is DISTRIBUTED. A set of string constants for the parameter executionMode.
