+ # Maximum bytes that may be logged as legacy log events
+ # (records posted to the "logs" table). Starting with Arvados

- # Setting this too high creates a risk that the dispatcher

- # containers (based on SupervisorFraction and MaxInstances)
- # that the cloud quota prevents them from running any child
- # containers.
+ # Setting this to 0 means the dynamic instance limit will

- # unnecessarily slow to start up new instances after a

- InitialQuotaEstimate: 16
+ # Situations where you may want to set this (to a value less
+ # than MaxInstances) would be when there is significant
