 title: Deferred response – Knowledge Base – kdb+ and q documentation
-description: Ideally, for concurrency, all messaging would be async. However, sync messaging is a convenient paradigm for client apps. Hence -30!x was added as a feature in V3.6, allowing processing of a sync message to be ‘suspended’ to allow other messages to be processed prior to sending a response message.
