/show/proc/status

URL: https://<aws.fqdn>/<aws.cluster.name>/gpudb-0/show/proc/status

Shows the statuses of running or completed proc instances. Results are grouped by run ID (as returned from /execute/proc) and data segment ID (each invocation of the proc command on a data segment is assigned a data segment ID).

Input Parameter Description

Name

Type

Description

run_id

string

The run ID of a specific proc instance for which the status will be returned. If a proc with a matching run ID is not found, the response will be empty. If not specified, the statuses of all executed proc instances will be returned. The default value is ''.

options

map of string to strings

Optional parameters. The default value is an empty map ( {} ).

Supported Parameters (keys)

Parameter Description

clear_complete

If set to true, if a proc instance has completed (either successfully or unsuccessfully) then its status will be cleared and no longer returned in subsequent calls. The default value is false. The supported values are:

true
false

run_tag

If input parameter run_id is specified, return the status for a proc instance that has a matching run ID and a matching run tag that was provided to /execute/proc. If input parameter run_id is not specified, return statuses for all proc instances where a matching run tag was provided to /execute/proc. The default value is ''.

Output Parameter Description

params

map of string to maps of string to strings

The string params passed to /execute/proc for the returned run IDs.

bin_params

map of string to maps of string to bytes

The binary params passed to /execute/proc for the returned run IDs.

input_table_names

map of string to arrays of strings

The input table names passed to /execute/proc for the returned run IDs.

input_column_names

map of string to maps of string to arrays of strings

The input column names passed to /execute/proc for the returned run IDs, supplemented with the column names for input tables not included in the input column name map.

output_table_names

map of string to arrays of strings

The output table names passed to /execute/proc for the returned run IDs.

options

map of string to maps of string to strings

The optional parameters passed to /execute/proc for the returned run IDs.

overall_statuses

map of string to strings

Overall statuses for the returned run IDs. Note that these are rollups and individual statuses may differ between data segments for the same run ID; see output parameter statuses and output parameter messages for statuses from individual data segments.
