I have a question about the recovery mechanism of a shard following a node restart.
Before restarting a node, I always disable the allocation (cluster.routing.allocation.enable = none).
I noticed that when the node is restarted, the shards of the indices for the current day are in the "initializing state". This step only lasts a few minutes and I am wondering what happens during this time.
- Is it the necessary time to apply the modifications which happened during the restart of the node ?
- Why do I see this "initializing state" for the indices of the day only ?
Thanks for your help,
