Engine pruning

When the TERR service reaches a certain percentage of capacity of usage, then the TERR service begins pruning TERR engines to free service resources.

Configuration property Default setting Description
engine.prune 10 The time, in seconds, that a TERR engine can be idle before the TERR service prunes it.
dynamic.prune.threshold 60 The TERR service capacity at which idle pruning is engaged, as a percentage value.
By default, when the TERR service reaches 60% capacity of usage, then it begins the idle-pruning process as specified by engine.prune.
  • Set to 0 to always prune when a TERR engine is idle.
  • Set to 100 to never prune when a TERR engine is idle.
