Opensearch Java Client is not showing up the creation date of an index in a _cat request

Opensearch Java Client Versions:

  • opensearch-rest-client (2.4.0)
  • opensearch-java (2.1.0)

Description:

I’m using a _cat request to get some information about the indices through the opensearch java client. When I check the response, the creation date of the index is not coming up.

As you can see, the creationDate of the index is not coming out.

If I make the request directly to elasticsearch, I get the creation date, as you can see below.

Is this a bug ??? Why the creation date of the index is not coming out in the opensearch java client

I'm trying to get index information, but I can't get the creation date using the opensearch java client

Solution

  • After test all the possible ways, I just ended using a rest call using the Springboot WebClient. The OpenSearch Java Client is very immature right now. There are some task that we can implement without any problem, but there are a lot of incomplete work in his implementation
