Method Details

findUnusedClusters

@Query(value="SELECT id FROM clusters WHERE status IN (:unusedStatuses) AND created < :clusterCreatedThreshold AND id NOT IN (SELECT DISTINCT(cluster_id) FROM jobs WHERE cluster_id IS NOT NULL) LIMIT :limit",
       nativeQuery=true)
Set<Long> findUnusedClusters(@Param("unusedStatuses")
 Set<String> unusedStatuses,
 @Param("clusterCreatedThreshold")
 Instant clusterCreatedThreshold,
 @Param("limit")
 int limit)

Find all the clusters that aren't attached to any jobs in the database, were created before the given time and have one of the given statuses.

Parameters:

unusedStatuses - The set of statuses a cluster must have to be considered unused

clusterCreatedThreshold - The instant in time which a cluster must have been created before to be considered unused. Exclusive.

limit - Maximum number of IDs to return

Returns:

The ids of the clusters that are considered unused

getClusterDto

@Query("SELECT c FROM ClusterEntity c WHERE c.uniqueId = :id")
@EntityGraph(value="Cluster.dto",
             type=LOAD)
Optional<ClusterEntity> getClusterDto(@Param("id")
 String id)

Find the cluster with the given id but also eagerly load all data needed for a cluster DTO.

Parameters:

id - The id of the command to get

Returns:

The ClusterEntity with all DTO data loaded or Optional.empty() if there is no cluster with the given id
