Can't find a way to set the number of replicas for an Elasticsearch index

[pvdbk]

OrchardCore version : 1.8.2

Problem

Each time an Elasticsearch index is created, a replica is created with the index. In our case this replica is not supported, as we work with a single-node cluster.

Solution

The creation of index should be managed via an interface, as many features in Orchard. Most of the work is done by ElasticIndexManager.CreateIndexAsync. The logic implemented there is too complex to be safely reworked. It could be good to split this logic in several public methods.

Alternatives

No alternative was found for this problem. When you create an index in the administrator board, everything is managed by classes without interface. We could add a background task to remove the replicas, but we would prefer an other solution.

Or maybe it should be exposed in an Elasticsearch specific setting.
