> We should dump user/system times in transaction to log on commit/rollback, if duration
of transaction more then threshold. I want to see in log on tx coordinator node:
> # Transaction duration
> # System time:
> #* How long we were getting locks on keys?
> #* How long we were preparing transaction?
> #* How long we were commiting transaction?
> # User time (transaction time - total system time) 
> # Transaction status (commit/rollback)
> The threshold could be set by system property and overwrite by JMX. We shouldn't dump
times, if the property not set.
