ExecuteProcRequest

public static final class ExecuteProcRequest.Options
extends Object

Optional parameters.

• CACHE_INPUT: A comma-delimited list of table names from inputTableNames from which input data will be cached for use in subsequent calls to GPUdb.executeProc(ExecuteProcRequest) with the use_cached_input option. Cached input data will be retained until the proc status is cleared with the clear_complete option of GPUdb.showProcStatus(ShowProcStatusRequest) and all proc instances using the cached data have completed. The default value is ''.
• USE_CACHED_INPUT: A comma-delimited list of run IDs (as returned from prior calls to GPUdb.executeProc(ExecuteProcRequest)) of running or completed proc instances from which input data cached using the cache_input option will be used. Cached input data will not be used for any tables specified in inputTableNames, but data from all other tables cached for the specified run IDs will be passed to the proc. If the same table was cached for multiple specified run IDs, the cached data from the first run ID specified in the list that includes that table will be used. The default value is ''.
• KIFS_INPUT_DIRS: A comma-delimited list of KiFS directories whose local files will be made directly accessible to the proc through the API. (All KiFS files, local or not, are also accessible through the file system below the KiFS mount point.) Each name specified must the name of an existing KiFS directory. The default value is ''.
• RUN_TAG: A string that, if not empty, can be used in subsequent calls to GPUdb.showProcStatus(ShowProcStatusRequest) or GPUdb.killProc(KillProcRequest) to identify the proc instance. The default value is ''.

The default value is an empty Map. A set of string constants for the parameter options.
