This article addresses some of the key highlights of the Service Broker in SQL Server 2017.
Service Broker in SQL Server offers native support effectively for queuing and messaging applications in a SQL Server Database Engine. In essence, this simplifies the process of application creation, where users can operate using multiple components of the database engine while communicating between different databases. Now developers may also look to use Service Broker for building reliable and distributed applications. Service Broker is a technology which allows users to perform queuing and messaging functions in between instances. The basic function or cycle of sending and receiving these messages creates a ‘conversation’. Each of these conversations forms a complete structure of channel of communication. Service Broker was first introduced in SQL Server in 2005 and since it has become an essential part of the software, which allows users to communicate between networks. It also allows users to share file provide access to different databases which helps in a better flow of communication within an organization.
Users can distribute workloads of data across different databases, without forming a complex communication programming using Service Broker. This reduces text and development work as Service Broker can handle communication paths with the context of the conversations. It also helps in improving performance.
For instance, a front-end database which supports Websites has the ability to store information and also quickly send process tasking tasks to its queue in its back-end databases. Here, Service Broker is responsible for ensuring that all these tasks are effectively managed with the given context of the said transactions to assure technical and reliable consistency.
Key Highlights of Service Broker in SQL Server 2017
There haven’t been any significant changes in Service Broker in SQL Server 2017. However, some of these changes have definitely helped in boosting SQL Server’s performance and interface. Service Broker has made it easier for developers to easily create interactive applications without any hassle. These are some of the changes which were last introduced in SQL Server 2012 update. Service Broker has definitely been updated into forming smoother and more refined channels of communication, which follow a descriptive collection of conversations. These following features haven’t been twisted since 2012 SQL Server update edition, however, they are working efficiently which is what is preventing the company from making any significant or minute changes in the software.
1. Now users can multicast Messages to several target services
Users can simply use SEND (Transact-SQL) syntax in a statement to roll out multicast or to send multiple messages in a network by using numerous conversation handles. Using this syntax user can save their time and energy by broadcasting a single message to as many as a user that they like.
2. Queues expose the time message have been queued up for
Queues also have an additional column, “message_enqueue_time” which shows the duration time of the message for which it has stayed in the given queue.
3. Users can disable their Poison Message Handling
In the updated version statements have the ability to disable or enable the poison message handling setting by inserting an on-of clause.
Even if you are running the SQL Server 2017 edition, you may encounter a corrupted mdf file. To deal with such situations and avoid any possibility of data loss, consider a specialized tool like DataNumen SQL Recovery.
