Method Detail

deprecateContainers

public void deprecateContainers(java.util.Collection<com.github.ambry.account.Container> deprecatedContainers,
                                java.util.Collection<java.lang.String> partitionIds)
                         throws CloudStorageException

Update newly deprecated containers from deprecatedContainers to CosmosDb since last checkpoint. This method is one of the two entry points in AzureContainerCompactor along with compactAssignedDeprecatedContainers(Collection).

Parameters:

deprecatedContainers - Collection of deprecated Containers.

partitionIds - list of partition ids from where the containers have to be removed.

Throws:

CloudStorageException - in case of any error.

compactAssignedDeprecatedContainers

public void compactAssignedDeprecatedContainers(java.util.Collection<? extends com.github.ambry.clustermap.PartitionId> assignedPartitions)

Compact blobs of the deprecated container from cloud. This method is one of the two entry points in the AzureContainerCompactor class along with deprecateContainers(Collection, Collection). Note that this method is not thread safe as it is expected to run in a single thread.

Specified by:

compactAssignedDeprecatedContainers in interface CloudContainerCompactor

Parameters:

assignedPartitions - the Collection of PartitionIds assigned to this node.

getLatestContainerDeletionTimestamp

public long getLatestContainerDeletionTimestamp()

Returns:

the latest container deletion timestamp.

shutdown

public void shutdown()

Shut down the compactor waiting for in progress operations to complete.

Specified by:

shutdown in interface CloudContainerCompactor
