Replication conventions

FailoverBehavior

This conventions tells the client how it should behave in a replicated environment when the primary node is unreachable and need to failover to secondary node(s). Detailed description you will find here.

Conventions.FailoverBehavior = FailoverBehavior.AllowReadsFromSecondaries;

ReplicationInformerFactory

This is called to provide replication behavior for the client. You can customize this to inject your own replication / failover logic by implementing IDocumentStoreReplicationInformer.

Conventions.ReplicationInformerFactory = (url, jsonRequestFactory) =>
	new ReplicationInformer(Conventions, jsonRequestFactory);

IndexAndTransformerReplicationMode

It allows to change the replication mode for index and transformer definitions when they are created (or changed) by the client code (AbstractIndexCreationTask.Execute / AbstractTransformerCreationTask.Execute). It is an enum type with [Flags] attribute applied. The possible values are:

  • None - neither indexes nor transformers are updated to replicated instances,
  • Indexes - all created indexes are replicated.
  • Transformers - all transformers are replicated.

By default both indexes and transformers are uploaded to the replication nodes:

Conventions.IndexAndTransformerReplicationMode = IndexAndTransformerReplicationMode.Indexes |
                                                 IndexAndTransformerReplicationMode.Transformers;
