There are a number of thread settings in aerospike, the most important ones probably service-threads, transaction-threads-per-queue, and migrate-threads. In general, for some are recommended to be equal to the number of cores, while others are static (e.g. migrate-threads is 1 by default). A few questions about that:
- in aws cores (aka vcpu-s) are actually virtual hyper threads so a 8 “core” box usually means a 4 core hyperthreaded box – do you recommend using the virtual core numbers or half of that?
- should the total number of threads configured add up to the total number of cores or should they be overallocated - e.g. do i want 1 migrate thread + 7 service threads on a 8 core box?
