List all indices using Java rest client

[PV2000 (PV)]

Hi,

• What is the best way to get a list of all indices in Elastic Search using Java ? I am using RestHighLevelClient.
• Also, is there a way to get only those indices that match a prefix ?

I see cat indices REST endpoint provides the capability,
cat indices API | Elasticsearch Guide [7.17] | Elastic , but I cant find any Java client example to invoke it.

What is the best way to get a list of all indices in Elastic Search using Java ? I am using RestHighLevelClient.

I dont know if best way but works:

    var response2 = getClient().indices().getMapping(new GetMappingsRequest().indices("*"),
        RequestOptions.DEFAULT);
    var indexes2 = response2.mappings().keySet()

Also, is there a way to get only those indices that match a prefix ?

Try this:

new GetMappingsRequest().indices("idx_te*")
