Elastic4s: How do I get all index names from ElasticSearch?

Question

I am using Elastic4s. I need to find all index names from an instance of ElasticSearch. What API shall I use?

Answer 1

For Elastic4s version: 6.5.0. You can get all the indices using catIndices api provided by Elastic4s.

Here's an example:

val resp = client.execute {
  catIndices
}

You can refer the official doc for more info.

Answer 2

In elastic 1.6.5 you can do,

val resp = client.execute {
  clusterState
}
