Create Proc

Creates an instance (proc) of the user-defined function (UDF) specified by the given command, options, and files, and makes it available for execution. For details on UDFs, see: User-Defined Functions

Input Parameter Description

Name	Type	Description
proc_name	string	Name of the proc to be created. Must not be the name of a currently existing proc.
execution_mode	string	The execution mode of the proc. The default value is distributed. Supported Values Description 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 access to any input or output table data.
files	map of string to bytes	A map of the files that make up the proc. The keys of the map are file names, and the values are the binary contents of the files. The file names may include subdirectory names (e.g. 'subdir/file') but must not resolve to a directory above the root for the proc. The default value is an empty map ( {} ).
command	string	The command (excluding arguments) that will be invoked when the proc is executed. It will be invoked from the directory containing the proc input parameter files and may be any command that can be resolved from that directory. It need not refer to a file actually in that directory; for example, it could be 'java' if the proc is a Java application; however, any necessary external programs must be preinstalled on every database node. If the command refers to a file in that directory, it must be preceded with './' as per Linux convention. If not specified, and exactly one file is provided in input parameter files, that file will be invoked. The default value is ''.
args	array of strings	An array of command-line arguments that will be passed to input parameter command when the proc is executed. The default value is an empty array ( [] ).
options	map of string to strings	Optional parameters. The default value is an empty map ( {} ). Supported Parameters (keys) Parameter Description max_concurrency_per_node The maximum number of concurrent instances of the proc that will be executed per node. 0 allows unlimited concurrency. The default value is '0'.

Output Parameter Description

Name	Type	Description
proc_name	string	Value of input parameter proc_name.
info	map of string to strings	Additional information.
