Hi, You should use write-behind mode only if it's acceptable for you to lose some updates to persistent store on node failures. Be vary of possible desync between persistent store and cache after node recovery. You can tune write-behind behavior as described here: https://apacheignite.readme.io/docs/persistent-store#configuration
