I’m running pure Write traffic (30K TPS, 1KB record size) with Aerospike 3.3.8 In-Memory + Disk Persistence. The “iostat” shows ~15 seconds of ~120MB/s disk writing for every interval of 60 seconds, and 0 MB/s for the rest of 60-15 = 45 seconds.
Any parameters can be tuned to let the disk activity smoothly? (spread out the disk writing as 15*120/60 = 30MB/s, instead of spikes as 120MB/s)
- Reduce the data loss in case of power lost, trade-off the performance and Durability of ACID.
- On Cloud to reduce the disk I/O impact for VMs each other in case of two VMs having block storage on the same physical disk.
