Answer 1

Your configuration is using the default timeout. Configure your RestClient as follows:

return 
  new RestHighLevelClient(
      RestClient.builder(
        HttpHost.create(__elasticEndpointUrl__))
          .setHttpClientConfigCallback( hacb -> hacb.addInterceptorLast(__interceptorHere__))
          .setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(__timeOutHere__)
          .setSocketTimeout(__**putHighValueHere**__)));
