Cassandra : isolated workloads -


i have 3 workloads.

  1. datacenter1 sharing data rest services - streaming ingest
  2. datacenter2 load bulk - analysis
  3. datacenter3 research

i want isolated workloads, going create 1 datacenter foreach workloads. objective of operation prevent heavy process consuming resources , gurantee hight availablity data.

is trying ?

during loadbulk on datacenter2, data availability on datacenter1 ?

short answer workload won't cause disruption of load across datacenter. how works follows:

conceptually when create keyspace, cassandra creates virtual data center (vdc). nodes similar workloads must assigned same vdc. segregating workload ensure (exactly) 1 workload ever executed @ vdc. long follow pattern, works.

data sync needs monitored under load on busy nodes thats normal concern on cassandra deployment.
