The SHOW JOBS statement lists all of the types of long-running tasks your cluster has performed in the last 12 hours, including:

These details can help you understand the status of crucial tasks that can impact the performance of your cluster, as well as help you control them.

To block a call to SHOW JOBS that returns after all specified job ID(s) have a terminal state, use SHOW JOBS WHEN COMPLETE. The statement will return a row per job ID, which provides details of the job execution. Note that while this statement is blocking, it will time out after 24 hours.

Considerations

  • The SHOW JOBS statement shows only long-running tasks. For an exhaustive list of jobs running in the cluster, use the SQL Audit Logging (Experimental) feature.
  • For jobs older than 12 hours, query the crdb_internal.jobs table.
  • Jobs are deleted after 14 days. This interval can be changed via the jobs.retention_time cluster setting.
  • While the SHOW JOBS WHEN COMPLETE statement is blocking, it will time out after 24 hours.

Required privileges

By default, only the root user can execute SHOW JOBS.

Synopsis

SHOW AUTOMATIC JOBS JOBS WHEN COMPLETE select_stmt JOB WHEN COMPLETE job_id

Parameters

Parameter Description
select_stmt A selection query that specifies the job_id(s) to view.
job_id The ID of the job you want to view.

Response

The output of SHOW JOBS lists ongoing jobs first, then completed jobs within the last 12 hours. The list of ongoing jobs is sorted by starting time, whereas the list of completed jobs is sorted by finished time.

The following fields are returned for each job:

Field Description
job_id A unique ID to identify each job. This value is used if you want to control jobs (i.e., pause, resume, or cancel it).
job_type The type of job. Possible values: SCHEMA CHANGE, BACKUP, RESTORE, IMPORT, and CREATE STATS.

For SHOW AUTOMATIC JOBS, the possible value is AUTO CREATE STATS.
description The statement that started the job, or a textual description of the job.
statement When description is a textual description of the job, the statement that started the job is returned in this column. Currently, this field is populated only for the automatic table statistics jobs.
user_name The name of the user who started the job.
status The job's current state. Possible values: pending, running, paused, failed, succeeded, or canceled.
running_status The job's detailed running status, which provides visibility into the progress of the dropping or truncating of tables (i.e., DROP TABLE, DROP DATABASE, or TRUNCATE). For dropping or truncating jobs, the detailed running status is determined by the status of the table at the earliest stage of the schema change. The job is completed when the GC TTL expires and both the table data and ID is deleted for each of the tables involved. Possible values: draining names, waiting for GC TTL, RocksDB compaction, or NULL (when the status cannot be determined).

For the SHOW AUTOMATIC JOBS statement, the value of this field is NULL.
created The TIMESTAMP when the job was created.
started The TIMESTAMP when the job began running first.
finished The TIMESTAMP when the job was succeeded, failed, or canceled.
modified The TIMESTAMP when the job had anything modified.
fraction_completed The fraction (between 0.00 and 1.00) of the job that's been completed.
error If the job failed, the error generated by the failure.
coordinator_id The ID of the node running the job.

     job_id     | job_type  |               description                 |...

Filter jobs

You can filter jobs by using SHOW JOBS as the data source for a SELECT statement, and then filtering the values with the WHERE clause.

copy
icon/buttons/copy
> SELECT * FROM [SHOW JOBS] WHERE job_type = 'RESTORE' AND status IN ('running', 'failed') ORDER BY created DESC;
     job_id     | job_type  |              description                  |...
+---------------+-----------+-------------------------------------------+...
 27536791415282 |  RESTORE  | RESTORE db.* FROM 'azure://backup/db/tbl' |...

Show automatic jobs

copy

> SHOW AUTOMATIC JOBS;
        job_id       |       job_type      |                    description                      |...

Filter automatic jobs

You can filter jobs by using SHOW AUTOMATIC JOBS as the data source for a SELECT statement, and then filtering the values with the WHERE clause.

copy
icon/buttons/copy
> SELECT * FROM [SHOW AUTOMATIC JOBS] WHERE status = ('succeeded') ORDER BY created DESC;
        job_id       |       job_type      |                    description                      | ...

  438235476849557505 | AUTO CREATE STATS   | Table statistics refresh for defaultdb.public.users | ...
(1 row)

Show schema changes

You can show just schema change jobs by using SHOW JOBS as the data source for a SELECT statement, and then filtering the job_type value with the WHERE clause:

copy
icon/buttons/copy
> SELECT * FROM [SHOW JOBS] WHERE job_type = 'SCHEMA CHANGE';
     job_id     | job_type        |              description                           |...
+---------------+-----------------+----------------------------------------------------+...
 27536791415282 |  SCHEMA CHANGE  | ALTER TABLE test.public.foo ADD COLUMN bar VARCHAR |...

Show job when complete

To block SHOW JOB until the provided job ID reaches a terminal state, use SHOW JOB WHEN COMPLETE:

copy
icon/buttons/copy
> SHOW JOB WHEN COMPLETE 27536791415282;
     job_id     | job_type  |               description                 |...
+---------------+-----------+-------------------------------------------+...
 27536791415282 |  RESTORE  | RESTORE db.* FROM 'azure://backup/db/tbl' |...
