Will be looking to restore specific indexes into different clusters.
Or should this be done sequentially?
I doubt that would cause any problems, no. S3 almost certainly has more bandwidth than you do
We wanted more information in this issue because we don't know if ES mutates something in a snapshot while it's restoring it because if it does that, Restoring a snapshot to multiple clusters might cause some problems?
No, because all (but one) of the clusters are using the repository in
readonly mode. Quoting the docs:
If you register the same snapshot repository with multiple clusters, only one cluster should have write access to the repository. All other clusters connected to that repository should set the repository to
