Is there a maximum number of objects that can be held by one Terracotta server instance?
The number of objects that can be held by a Terracotta server instance is two billion, a limit imposed by the design of Java collections. It is unlikely that a Terracotta cluster will need to approach even 50 percent of that maximum. However, if it does, other issues may arise that require the rearchitecting of how application data is handled in the cluster.
