@wmccarley Thank you for your guidance and recommendations. I will review the IOPS usage during that time. The CPU usually goes up and stays around 100% for the brokers which are replicating data but will check on the journal and ledgers iops. In a nutshell, the cluster can handle iops for the regular operations but may not have enough iops available for added iops during cluster recovery. I am using c5.xlarge for both bookkeeper and broker cluster. We barely hit around 2.5% of journal cluster but i have kept the cluster at around 500Gb to keep the additional iops that come with it. 3% makes sense with backup. ~12.5Gb) During initial evaluation, i had considered i3.xlarge instances with 1TB GP2 volumes for ledgers but we went with 500Gb GP2 for journal and 1TB st1 for ledgers on c5.xlarge instances. I will evaluate i3.xlarge instance size again. I will also look into the compaction rate ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
