I want to make 2 clients concurrently calculate some values from a cache that read from a database, and store the result in the database. I can't use atomic cacheAtomicityMode as there is no lock so that the calculation might get an old value. I also need a backup to avoid lost cache when a node fail. Let's say I run 2 servers, and 2 clients. Right now, I'm able to do 50_000 transactions for two rows in 70 seconds (around 1400 TPS). If it's possible, I want to increase the TPS.
My initial configuration is like this: Server configuration: 1. CacheAtomicityMode = transactional 2. Read Through, Write Through, and Write Behind = true 3. Cache Mode = partitioned 4. Backup = 1 5. Query entities for my table 6. cacheStoreFactory for my CacheStore 7. DiscoverySPI which I set to my localhost Client configuration have the same configuration as the server excluding ReadThrough, WriteThrough, WriteBehind, QueryEntities, and CacheStoreFactory. The Transaction Concurrency is pessimistic while transaction isolation is repeatable_read. I didn't set Write synchronization mode (which by default will be PRIMARY_SYNC). The transaction procedure is similar with the one in Ignite Documentation [1]. Any suggestions?
