Hi, I have 8 servers in my Cassandra Cluster. Each server has 64 GB ram and 40 Cores and 8 SSD. Currently I have below config in Cassandra.yaml:
concurrent_reads: 32 concurrent_writes: 64 concurrent_counter_writes: 32 compaction_throughput_mb_per_sec: 32 concurrent_compactors: 8 With this configuration, I can write 1700 Request/Sec per server. But our desired write performance is 3000-4000 Request/Sec per server. As per my Understanding Max value for these parameters can be as below: concurrent_reads: 32 concurrent_writes: 128(8*16 Corew) concurrent_counter_writes: 32 compaction_throughput_mb_per_sec: 128 concurrent_compactors: 8 or 16 (as I have 8 SSD and 16 core reserve for this) Please let me know this is fine or I need to tune some other parameters for speedup write.
