Hi folks

In my current is clustered to have 10 thousand plus shards available.

Suppose I need to restart one node. Is there any restart policy for recovering all shards quickly?

First, reducing the number of shards helps in general regarding performance, not only when restarting.

Before shutting down, you may want to execute a [synced flush](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/indices-synced-flush-api.html), as this will speed up recovery greatly.
