Hi! I have a question, is it normal that if WAL is deactivated for a persisted cache when the server node(s) is restarted, the persisted content of the cache is completely destroyed?
I need to disable WAL for large heavy ingestion processes, but eventually ingestion may fail (OS, machine crash), so WAL state is not re-enabled after ingestion. On this situation if I restart a server node, cache persistent directory is deleted and recreated again, so data is lost. Thanks! This is the method that do this hell thing org.apache.ignite.internal.processors.cache.persistence.file.FilePageStoreManager.beforeCacheGroupStart Process to replicate it: 1. Start one or more server nodes with native persistence enabled 2. Create a cache (natively persisted) and store some data 3. Disable WAL for cache - ignite().cluster().disableWal("TheCacheName") 4. Restart server/s nodes 5. Check cache directory was deleted and recreated again, all data was lost.
