I have some indexes with name test-1-in, test-2-in, test-3-in. I want to do _cat/indices/test-*-in from JAVA API. How to do this?
You can't call cat API from transport client. It's a REST API only.
But you can look at the source code to see how it's implemented behind the scene and do the same thing from the transport client.
Thanks @dadoonet. I dug into _cat implementation and found out what they are doing. Here it is:
final ClusterStateRequest clusterStateRequest = new ClusterStateRequest(); clusterStateRequest.clear().metaData(true); final IndicesOptions strictExpandIndicesOptions = IndicesOptions.strictExpand(); clusterStateRequest.indicesOptions(strictExpandIndicesOptions); ClusterStateResponse clusterStateResponse = client.admin().cluster().state(clusterStateRequest).get(); clusterStateResponse.getState().getMetadata().getIndices()
This will give all indexes. After that the reg ex matching has to be done manually.
