Hello

We are seeing a problem with the growth of the job queue for the EXECUTION_SWEEP job type.

The job cannot delete a job for type EXECUTION_SWEEP in the "task" table because there is no entry for the execution_id.

for example:

registry=# SELECT COUNT(1) FROM execution WHERE vendor_type = 'EXECUTION_SWEEP';
 count
-------
   341
(1 row)

registry=# SELECT COUNT(1) FROM execution WHERE vendor_type = 'EXECUTION_SWEEP' AND status = 'Error';
 count
-------
   219
(1 row)

registry=# SELECT COUNT(1) FROM execution WHERE vendor_type = 'EXECUTION_SWEEP' AND status = 'Stopped';
 count
-------
   105
(1 row)

registry=# SELECT COUNT(1) FROM execution WHERE vendor_type = 'EXECUTION_SWEEP' AND status = 'Success';
 count
-------
     2
(1 row)

registry=# SELECT COUNT(1) FROM execution WHERE vendor_type = 'EXECUTION_SWEEP' AND status = 'Running';
 count
-------
    15
(1 row)

The "task" table does not have entries for executions in the "Error" status for vendor_type = 'EXECUTION_SWEEP'

Q:

1. How fix it?
2. Can I remove entries for the EXECUTION_SWEEP job from the "execution" and "task" table myself?

@wieldes Hi, could you try to execute the above same SQLs on the task table?

I noticed that sweep IMAGE_SCAN executions took long time which caused the high latency for the EXECUTION_SWEEP job.

Could you also try to check the size of the of IMAGE_SCAN vendor type includes execution and task table?

@chlins

registry=# SELECT COUNT(1) FROM execution WHERE vendor_type = 'IMAGE_SCAN';
  count
---------

registry=# SELECT COUNT(1) FROM task WHERE vendor_type = 'IMAGE_SCAN';

(1 row)

A lot of records for IMAGE_SCAN....

Some time ago we disabled the automatic image scan.

Will it be safe to remove IMAGE_SCAN records from task and execution tables?

If you don't need to keep the scan status or report for the artifacts, you can manually delete these records. Even after deletion, you can still re-trigger the image scan to re-analyze vulnerabilities for the artifacts.
