Hi,
Found some related topics but no actual answer.
We run daily snapshots in production, and every morning we wipe our test cluster and do a full restore. This way we test our backups and our staff has playground environment with very good data.
This worked fine with 5.x, took a bit less than an hour to complete, acceptable. However since switching to 7.x, it does not even complete in a day.
An empty index took 9.2m to recover, according to _cat/recovery, most of the empty ones took around that time.
I have tried fiddling with the settings:
"cluster": {
"routing": {
"allocation": {
"node_concurrent_recoveries": "10",
"node_initial_primaries_recoveries": "20"
}
}
},
"indices": {
"recovery": {
"max_bytes_per_sec": "250mb",
"max_concurrent_file_chunks": "5"
}
}
But that does not change anything to the speed.
Is there anyway to get back to decent speed for recovery or is our use case not something supported anymore?
Thanks in advance
