Replicate PUT Job

Description

Replicates a job from another BlackPearl system to this BlackPearl system, ensuring that the objects are recognized as identical across the systems on which replication is performed. Clients must provide the response payload returned by Modify Active Job on the source BlackPearl system as the request payload for the Replicate PUT Job on the target system.

Requests

Syntax

PUT http[s]://{datapathDNSname}/_rest_/bucket/{UUID, name, or other unique attribute for the bucket}?operation=START_BULK_PUT​&replicate[&priority=URGENT|HIGH|NORMAL|LOW]

To determine the UUID for a bucket, see Get Buckets - Spectra S3.

where the response elements are defined as follows:

Parameter	Description
MasterObjectList	The container for the response.
Aggregating	Whether the job can have additional PUTs or GETs appended to it. Jobs aggregate if created with the aggregating request parameter set to TRUE, or if created by the BlackPearl system in response to Amazon S3 PUT and GET requests. Values: TRUE, FALSE
BucketName	The name of the bucket that is acted on by the job request.
CachedSizeInBytes	The amount of data that has been transferred to the cache for this job. For RequestType=PUT, this is the amount of data successfully transferred to the BlackPearl Converged Storage System from the client.
ChunkClient ProcessingOrder Guarantee	Specifies whether the job chunks will be processed in order. Values: IN_ORDER, NONE
CompletedSizeIn Bytes	The amount of data that is completely processed for this job. For RequestType=PUT, this indicates the amount of data written to all permanent data stores.
EntirelyInCache	Whether all objects in the job are in the BlackPearl cache. Values: TRUE, FALSE
JobId	The UUID for the job.
Naked	Whether the job was created as the result of a native S3 command (TRUE) or a Create Bulk GET/PUT/VERIFY job command (FALSE). Values: TRUE, FALSE
Name	The name assigned to the job for tracking.
OriginalSizeInBytes	The full size of the job.
Priority	The priority for processing this job. The job priority determines the assigned resources and processing order. Values: CRITICAL, URGENT, HIGH, NORMAL, LOW, BACKGROUND
RequestType	Type of job request. Values: PUT
StartDate	The date and time the job was started in the format YYYY-MM-DDThh:mm:ss.xxxZ.

UserId	The UUID for the user who initiated the job.
UserName	The username of the user who initiated the job.
Nodes	A container for information about all BlackPearl nodes.
Node	A container for information about a single BlackPearl node.
EndPoint	The IP address or DNS name of the BlackPearl node.
Id	The UUID for the node.
Objects	Container for information about the objects in one chunk.
ChunkId	The UUID for the job chunk.
ChunkNumber	The position of the chunk within the job.
Object	The container for information about a single object.
Id	The UUID for the object.
InCache	Indicates if the object is currently in cache on the BlackPearl Converged Storage System. Values: TRUE, FALSE
Latest	Whether this version of the object is the latest. Values: TRUE, FALSE
Length	The length in bytes of the object.
Name	The name of the object.
Offset	The offset in bytes from the start of the object.
