## The transactor will write a heartbeat into storage on this interval.
## A standby transactor will take over if it sees the heartbeat go
## unwritten  for 2x this interval. If your transactor load leads to
## long gc pauses, you can increase this number to prevent the standby
## transactor from unnecessarily taking over during a long gc pause.
