Re: Restore data from Ignite snapshots

Hello, You don't need to stop the cluster or delete/move any snapshot files in case you are using the restore procedure from the control.sh, so the following should work: - create snapshot - stop the caches you are intended to restore - run ./control.sh --snapshot restore snapshot_1 --start Can y

Re: Restore data from Ignite snapshots

Hi, So the way I am thinking to use it is if we lose the EBS volume and we need to restore the cluster state back. I would have a secondary EBS as my snapshot directory so I can restore from it. It means Application would need to be restarted after EBS data is copied back to the work directory. I s

Re: Server cache reads less number of entries than number of entries put by client cache

Yes, that I am sure, because the keys are generated using ignite uuid, which internally is based on hostname, and all the clients are hosted on machines with unique hostnames. On Wed, Feb 2, 2022 at 3:23 PM Pavel Tupitsyn wrote: > Are you sure that all entry keys are unique? > E.g. if you do 500

Re: Server cache reads less number of entries than number of entries put by client cache

That's correct, but this is when we use Pessimistic + Repeatable_Read transaction at Server side where we are using an iterator to read, remove and insert into new cache in the transaction. And this issue is not observed every time, but intermittently. And note that, if I don't use transactions or
