Replication management

Replication mappings

Introduction

DCT 9.0.0 introduces the feature to differentiate between the replicated objects and original objects in case of a parent and replicated engines, both are registered with DCT.

Prerequisites

One parent and one replicated engine is required with few replicated dSources and VDBs.

User interface

• Convenient separation between the replicated objects(VDB/dSource/environments) and original objects.

  

• Users can filter the replicated object using the advanced filter.

  

• All the actions on the replicated objects are disabled.

  

• The status of the replicated objects are N/A.

• On the VDB provisioning wizard, replicated objects(VDB/dSources) are marked as replicated.

  

API

Below are the list and search APIs, updated to return three additional fields (is_replica, namespace_id, namespace_name):

1. Sources
   GET:  /sources
   GET: /sources/{sourceId}
   POST: /sources/search

2. VDBs
   GET: /vdbs
   GET: /vdbs/{vdbId}
   POST: /vdbs/search

3. dSources
   GET: /dsources
   GET: /dsources/{dsourceId}
   POST: /dsources/search

4. CDBs
   GET: /cdbs
   GET: /cdbs/{cdbId}
   POST: /cdbs/search

5. VCDBs
   GET: /vcdbs
   GET: /vcdbs/{vcdbId}
   POST: /vcdbs/search

6. Environments
   GET: /environments
   GET: /environments/{environmentId}
   POST: /environments/search

7. Dataset-groups
   GET: /groups
   GET: /groups/{groupId}
   POST: /groups/search

8. Timeflows
   GET: /timeflows
   GET: /timeflows/{timeflowId}
   POST: /timeflows/search

9. Policies
   GET: /virtualization-policies
   GET: /virtualization-policies/{policyId}
   POST: /virtualization-policies/search

10. Snapshots
    GET: /snapshots
    GET: /snapshots/{snapshotId}
    POST: /snapshots/search

Below are the three fields added in response of these APIs:

1. is_replica: Boolean telling that this object id replicated or not.

2. namespace_id: This field will only come for replicated objects and is essentially the namespace id of the replicated object.

3. namespace_name: This field will only come for replicated objects and is essentially the namespace name of the replicated object.
