Aspnix mysql database server name3/25/2023 Ideally , ProxySQL is designed to provide a transparent read/write split of the workload to allow you to load balance and deploy a scale out architecture with MySQL, but you can also use it with a single server with no replicas between the application and Azure Database for MySQL to bypass requirement. ![]() ![]() ![]() ProxySQL is a high-performance MySQL proxy that sits between the application and the Azure Database for MySQL service. For such scenarios, you can use the ProxySQL load balancer proxy solution to broker the incompatibility between the application and Azure Database for MySQL. However, we have seen in some rare scenarios, using legacy drivers that don’t allow special character such as or some legacy applications that doesn’t allow changing the connection string in this format causes unforeseen errors. In addition, we are also working with the community to make it seamless for developers to connect to Azure Database for MySQL server. We have seen that most, if not all, connection drivers support this format, and hence it should be straight forward for developers or customers to use this format. For accurate connection redirection at the gateway, you are required to specify userid in the Hope this addresses the question on why this format is required. As the servername in full qualified format (.) is primarily meant to reach the regional gateway service, specifying hostname just in the connection string may not be enough to reach the target server. The gateway is a shared resource in Azure region and every incoming request (new connection or subsequent queries after session is established) to the gateway needs to specify the target server it needs to connect. In other words, the gateway will transparently r edirect the incoming connections to your active server at any given time to ensure the failover to a new compute server post planned or unplanned events doesn’t require you to change the connection string. In the above architecture, the gateway ensures transparent failover for the client application s. During planned/unplanned failovers or scale up/down events, a new container is provisioned, t he storage with data files is mapped to the new container and database is brought online, thereby providing high availability, and elasticity at reduced cost. The d atabase engine runs on a proprietary compute container (not docker container), while data files reside on Azure premium storage with three locally redundant synchronous copies of the database files. T he architecture separate s the compute and storage. The design is optimized for high availability, and elasticity. Below is the architecture for Azure D atabase for MySQL. To understand this requirement for Azure Database for MySQL, you first need to understand the underlying architecture and design of the service. C / C + + - MariaDB Connector/C : since version 3.0.5+.Java - MariaDB Connector/J : since version 2.2.5+.T he following is the list of drivers which no longer require this format : Further, we have also worked with the community and up dated some of the drivers which no longer require you to specify th is format. It ’s also important to note that all popular driver framework s viz JDBC, PHP, ADO.Net, Nodejs, Python, Go lang, etc. As mentioned in the documentation, when connecting to the service, the username in the connection string for authentication needs to be specified in the format. ![]() Let’s get started.įor those new to the Azure Database for MySQL service or un familiar with what I am talking about here, let me quickly summarize the requiremen t. In this blog post, I try to address this question by help ing you understand the requirement, and also share a tip if in some scenarios you can not afford to accommodate this requirement. This question is frequently asked by developers and / or our customers new to the service. You m ay be pondering th e question in the title wh ile using the Azure Database for MySQL service for the first time.
