Hi Team,

every day during UTC 00:00:00 we start receiving this error( failed to process cluster event (put-mapping) within 30s ). will the mappings be put all the data nodes ?? i mean will this API hit all the data nodes and timeout if no response from any of them ?

Thanks

How many daily indices do you have in the cluster? How many indices and shards in total? Which version of Elasticsearch are you using?

There are many new indices which gets created every day. but this started happening only after we added some warm nodes with lower capacity. So wanted to know if the put mapping have to be applied across all nodes . and these lower capacity nodes would not respond that quickly.

Any update to the cluster state, e.g. mapping updates, shard creation, shard movement etc, need to be propagated to all nodes before completion. Having lots of updates at the same time combined with slow or overloaded nodes could therefore cause problems.

How many indices do you create every day? How many indices and shards do you have in the cluster? What is the total size of these on disk?
