A quota is a configuration object specifying a maximum number of objects and a maximum individual and total size for each of three types of size.

Each maximum value is optional: when set to zero is ignored.

Partitions can be associated with a quota, setting in this way the maximum number of objects and/or the maximum sizes for the objects belonging to the partition.

There's a quota checks when an object is created or modified: a QuotaException is thrown if any of the quota limits are exceeded (maximum number of objects in the partition, maximum size, maximum total size in the partition).
