Re: Failed to get Cassandra DataSource cause Spring application context wasn't injected into CassandraCacheStoreFactory

Hi, 1) to inject Spring Bean to the client config, do you have a working example of do this for Ignite? I am new to Spring and Ignite. I thought I had done this with the below code. What ami I missing? 2) As of today, whether I have a predefined server cache or not, I keep getting this

Note that, if you’re using persistence, the recommendation is to use StatefulSets so that the nodes are added/removed in a predictable way. https://apacheignite.readme.io/docs/stateful-deployment Regards, Stephen > On 14 Feb 2019, at

Re: Procedure for scale in and scale out of ignite nodes

Hello! If you have backups factor of 1 then you can stop a node without data loss, then wait until rebalance is complete. So you should only remove nodes by one. You can add multiple ones at a time. Unfortunately there is no way to take node out of topology without stopping it. Regards, --
