today，my cluster has a warning ：maximum shards open 3000；
How should I do？
As large number of small indices and shards in a cluster can lead to performance and stability problems, there is now a soft limit to the number of shards each data node can hold. This is set quite high and is there to protect you. I would therefore recommend looking at how you shard your data and aim to reduce the number of shards in the cluster rather than increase the soft limit.
Thank you! I get it.
