River Plugin should wait until a specific mapping is added and then it should index the documents

Elastic Stack Elasticsearch
1

Hello!

I have to create a river plugin that index documents from a
PostgreSQL database. My problem is that my plugin should wait until a
specific mapping is added and then it should index the documents.

Is there any possibility to do this, or how can I tell the plugin that it
should wait until the mapping is added?

Thanks a lot!

Best regards,

Isabella

Hello!

I have one more question regarding the mappings. Does anyone know if there
is a possibility to get all mappings, that are defined in ES via Java API?
So I would like to receive all defined mappings, but without specifying the
index name or the type name. I didn't found anything in the ES
documentation.

Thanks a lot.

Best regards,
Isabella

For an example, look
at org.elasticsearch.rest.action.admin.indices.mapping.get.RestGetMappingAction

The trick is to issue a cluster state request

    ClusterStateRequest clusterStateRequest =

Requests.clusterStateRequest()
.filterRoutingTable(true)
.filterNodes(true);

In the returned result, all indices and mappings can be filtered out.
