Hi, my cluster has 4 nodes with 3 shards and 1 replica. Every node has 16G RAM and 8 cores CPU. About 50-60G data per day and now there's 55 indices, 234 shards and 2T total data.
The GC problem is a little serious, and how could I improve it?
Besides, I found that when I query through Dev Tools, it would return bad gateway and timeout sometimes and the index rate become very slowly. In addition, when I display the dashboard, the index rate would become very slowly too. How can I improve this problem?
thank you in advance
