Support for Pregel API(s) about python-arango HOT 7 CLOSED

Hi @akki

I just took a quick look and it seems there is no HTTP REST API support for Pregel yet from ArangoDB.
So unfortunately it is not possible to add it to python-arango.
And no I am not in the slack channel but you can always email me directly at [email protected].

@joowani Is it /_api/control_pregel? I am not very sure though, but maybe you can understand this.

Hi, just a quick comment:
I did not publicily document the http API for pregel yet, but I am fairly confident that we will not change the current API until we release ArangoDB 3.3
So if you like you can go ahead and implement it. Some example REST calls:

Start a pregel job, is just a POST requiest, the response will contain the pregel job-id

POST /_api/control_pregel
{"algorithm": "pagerank", "graphName":"abc"}

Check the pregel job status

GET /_api/control_pregel/<job-id>
{
    "state" : "running",
    "gss" : 12,
    "totalRuntime" : 123.23,
    "aggregators" : {...},
    "sendCount" : 3240364978,
    "receivedCount" : 3240364975
  }

Cancel a pregel job

DELETE /_api/control_pregel/<job-id>

Oh I see thanks @graetzer.
I will take a look and add it to the next release.

Hi @akki and @graetzer,

I've added the Pregel API to python-arango in the latest release. Please check it out and feel free to reopen this issue if you see any problems.

Thanks a lot for the efforts @joowani

Hi @joowani @graetzer @akki thank you for your help. But this does not return the pregel result. And also how can I set storage to false to get pregel result in memory.
