We have an ES cluster with 4 nodes - 3 data nodes of which 2 act as master node also and 1 coordinating node on which Kibana is configured.
We are loading data into Elasticsearch index from Kafka using confluent elasticsearch sink connector. Considering daily indices, the total data we currently have is 44 indices and 110 shards(90GB size, 177 million documents)
While checking on performance of Kibana visualizations, it is taking around 20seconds to load. It would be great if you can help in improving this performance as expected response time for Kibana visuals is less than 5 seconds.
Thanks in advance.
