SQL Server Service Broker is a feature of SQL Server that provides native support for messaging and queuing within the SQL Server Database Engine. It allows developers to create sophisticated applications that can communicate between databases and build distributed, reliable applications without having to program complex communication and messaging internals.
Here’s an overview of what Service Broker offers:
- Messaging and Queuing: Service Broker facilitates in-database messaging by allowing applications to send and receive messages within SQL Server. It uses a conversation-based approach to ensure messages are processed in the order they are sent and received exactly once.
- Asynchronous Processing: It supports asynchronous message processing, enabling applications to perform tasks without waiting for a response. This can improve the performance of applications by allowing them to continue processing other tasks while waiting for messages to be processed.
- Transactional Integrity: Service Broker ensures that message processing is integrated with SQL Server’s transactional model, providing reliability and consistency.
- Scalability and Reliability: By distributing workloads across multiple databases, Service Broker can help scale applications and improve their reliability.
- Security: It includes built-in support for secure message delivery, including certificate-based security to protect sensitive messages and control access to services.
Developers use Service Broker by creating services and queues within the database. Services are endpoints for communication, and queues store the messages until they are processed. Messages are sent using the SEND Transact-SQL statement and received using the RECEIVE command.
Service Broker is particularly useful for applications that require distributed transactions and need to ensure data consistency across multiple databases. It’s also beneficial for complex event processing and integrating SQL Server with other systems¹².
