Hi, CacheWriteSynchronizationMode defines the behavior of cache during modification operations. I mean IgniteCache#put(), #remove() etc. For example, in case of 'PRIMARY_SYNC', a thread that executes modification operation will wait for completion of operation on primary node only, backups will be updated asynchronously. If 'FULL_SYNC' is used than a thread will wait for responses from all participated nodes (from primary node and all backups).
hope this helps.
