SYS.PROJECT.HISTORY.JOBS

The sys.project.history.jobs table contains the historical metadata for the jobs in a project.

Syntax 
SELECT *
FROM sys.project.history.jobs
note

Dremio refreshes the data in sys.project.history.jobs once per hour, so it usually takes about 1 hour for query information to appear. If a query is run soon after Dremio's hourly refresh and takes a long time to finish, it could take more than 1 hour for the query's data to appear in the sys.project.history.jobs table.

Fields​

FieldData TypeDescription
job_idvarcharThe UUID to identify the job.
statusvarcharThe state of the job.
Enum: CANCELED, COMPLETED, FAILED
query_typevarcharThe mechanism used to submit the job.
Enum: ACCELERATOR_CREATE, ACCELERATOR_DROP, ACCELERATOR_EXPLAIN, FLIGHT,INTERNAL_ICEBERG_METADATA_DROP, JDBC, UI_EXPORT, UI_INTERNAL_PREVIEW, UI_INTERNAL_RUN, UI_PREVIEW, UI_RUN, METADATA_REFRESH, ODBC, PREPARE_INTERNAL, REST, UNKNOWN
user_namevarcharThe username of the user who submitted the job. For jobs that are triggered by Dremio, this value is $dremio$.
queried_datasets[varchar]An array representation of the fully-qualified dataset (table and view) names referenced by the job.
scanned_datasets[varchar]An array representation of the fully-qualified table names or reflection IDs scanned during the process.
Note: The scanned datasets are often different from the queried_datasets.
execution_cpu_time_nsintegerThe time (in microseconds) spent executing the job.
attempt_countintegerThe number of attempts that the job was attempted.
submitted_tstimestampThe date and time when the job was submitted to the system.
attempt_started_tstimestampThe date and time when latest attempt of the job was started. In most cases, this will be the same value as submitted_ts.
metadata_retrieval_tstimestampThe date and time when the metadata retrieval phase of the job started.
planning_start_tstimestampThe date and time when the planning phase of the job started.
query_enqueued_tstimestampThe date and time when the job was first submitted to the engine.
engine_start_tstimestampThe date and time when the engine replica start up was triggered.
execution_planning_start_tstimestampThe date and time when the execution planning phase of the job started.
execution_start_tstimestampThe date and time when the job started processing on the engine replicas.
final_state_tstimestampThe date and time when the job execution reached a final state (complete, failed, or canceled).
submitted_epochintegerThe date and time (in epoch nanoseconds) when the job was submitted to the system.
attempt_started_epochintegerThe date and time (in epoch nanoseconds) when this attempt started. In most cases, this will be the same value as submitted_epoch.

planning_start_epochintegerThe date and time (in epoch nanoseconds) when the planning phase of the job started.

rows_returnedintegerThe number of rows returned by the job.
bytes_returnedintegerThe number of bytes returned by the job results.

memory_availableintegerThe memory allocated to the job.
error_msgvarcharThis value will contain the error message that resulted from the job if the job failed; "" otherwise.

{ "reflection_id": [The UUID of the reflection], "reflection_type": [RAW, AGGREGATE, or EXTERNAL], "dataset_id": [The UUID of the dataset that the reflection is on.], "dataset_name": [The name of the dataset that the reflection is on.], "materialization_id": [The UUID to identify the materialization], "chosen" - [true if this materialization was chosen for this job; false otherwise.]
