New attributes for configuring address limits for paging

You can configure the following new attributes to set individual and global address limits based on the number of messages.

max-size-messages is the maximum number of messages allowed for the address before the broker executes the policy specified for the address-full-policy. The default value is -1, which means that there is no message limit.

global-max-messages is the total number of messages that the broker can use for all addresses. When this limit is reached, for the address associated with an incoming message, the broker executes the policy that is specified as a value for the address-full-policy. The default value is -1, which means that there is no message limit.

Note

If limits that are set for the max-size-bytes or global-max-size attributes are reached before the limits set for the max-size-message or global-max-messages attributes, the broker executes the address-full policy.
