sp.listStreamProcessors() (mongosh method)

Definition

sp.listStreamProcessors()

New in version 7.0. :

Returns documents for each named Stream Processor on the current Stream Processing Workspace. Each document provides descriptive information including the name, current state, and pipeline of a stream processor.

Compatibility

This method is supported in Atlas Stream Processing Workspaces.

Syntax

The sp.listStreamProcessors() method has the following syntax:

sp.listStreamProcessors(
  {
   <filter>
  }
)

Command Fields

sp.listStreamProcessors() takes these fields:

Field	Type	Necessity	Description
`filter`	document	Optional	Document specifying which fields to filter stream processors on. If you provide a filter, the command will only return those processors which match the values for all the fields you specify.

Behavior

sp.listStreamProcessors() returns documents describing all of the named stream processors on the current stream processing workspace to STDOUT.

Access Control

The user running sp.listStreamProcessors() must have the atlasAdmin role.

Example

The following example shows an expected response from sp.listStreamProcessors() when the command is called without any filter:

sp.listStreamProcessors()

1 {
2   id: '0135',
3   name: "proc01",
4   last_modified: ISODate("2023-03-20T20:15:54.601Z"),
5   state: "RUNNING",
6   error_msg: '',
7   pipeline: [
8     {
9       $source: {
10         connectionName: "myKafka",
11         topic: "stuff"
12       }
13     },
14     {
15       $match: {
16         temperature: 46
17       }
18     },
19     {
20       $emit: {
21         connectionName: "mySink",
22         topic: "output",
23       }
24     }
25   ],
26   lastStateChange: ISODate("2023-03-20T20:15:59.442Z")
27 },
28 {
29   id: '0218',
30   name: "proc02",
31   last_modified: ISODate("2023-03-21T20:17:33.601Z"),
32   state: "STOPPED",
33   error_msg: '',
34   pipeline: [
35     {
36       $source: {
37         connectionName: "myKafka",
38         topic: "things"
39       }
40     },
41     {
42       $match: {
43         temperature: 41
44       }
45     },
46     {
47       $emit: {
48         connectionName: "mySink",
49         topic: "results",
50       }
51     }
52   ],
53   lastStateChange: ISODate("2023-03-21T20:18:26.139Z")
54 }

The following example shows an expected response if you invoke sp.listStreamProcessors() filtering for only those stream processors with a state of running.

sp.listStreamProcessors({"state": "running"})

1 {
2   id: '0135',
3   name: "proc01",
4   last_modified: ISODate("2023-03-20T20:15:54.601Z"),
5   state: "RUNNING",
6   error_msg: '',
7   pipeline: [
8     {
9       $source: {
10         connectionName: "myKafka",
11         topic: "stuff"
12       }
13     },
14     {
15       $match: {
16         temperature: 46
17       }
18     },
19     {
20       $emit: {
21         connectionName: "mySink",
22         topic: "output",
23       }
24     }
25   ],
26   lastStateChange: ISODate("2023-03-20T20:15:59.442Z")
27 }
