RE: Loosing cache data when persistence is enabled

If nodes are partially offline and still in baseline, as was mentioned earlier — you really can loose your data check for example : [1  https://apacheignite.readme.io/docs/partition-loss-policies ] [2]  https://www.gridgain.com/docs/latest/developers-guide/partition-loss-policy   if all nodes ar

Re: C#/.NET: Possible to assign different nodes different roles?

It is possible to do this via node filters or attributes. We use differentiated fleets of client nodes that interact with server nodes to pull data processed at the server node level and then further process it at a cluster level. We assign a 'ROLE' attribute to each node and then filter those nod

C#/.NET: Possible to assign different nodes different roles?

Hello, I was assigned a POC where a cluster should not have a single point of failure -- more specifically, each node should be assigned a different role. This means that loading the cache, querying, storage, etc. would be seen as their own individual roles and therefore kept separate, hosting on d

Hi Ilya, I have a question related to this : >>Then, WAL will usually only grow and db/ will grow too, they will not shrink from the deletion of data from caches. Dropping a cache will free space. >>This is tolerable because modern server instances are usually single-purpose. You expect an insta

Hi Dimitry and community, Is this still true? My intention is to do it between versions 2.7.6 and 2.8.1/2.9. Basically, I want to only update the docker image keeping the volumes so that I can recover the persisted data. I couldn't find documentation regarding this topic. On the other hand, releas

Re: Loosing cache data when persistence is enabled

Hi Beela, could the root cause be that you had changes in your baseline topology when you saw the data loss? According to my understanding and the answer I got on my question http://apache-ignite-users.70518.x6.nabble.com/Ignite-persistence-Data-of-node-is-lost-after-being-excluded-from-baseline-t
