JIRA: https://jira.spring.io/browse/INT-3642 Currently, `removeMessageFromGroup` rebuilds the group on every removal. In every case where this method is used in the framework, the result is not used. Add `removeMessagesFromGroup` that removes a collection of messages and returns no result. INT-3642: Polishing - PR Comments INT-3642: Polishing and Fix Group Metadata Size
