问题描述
在传统的网络服务器中，您将拥有一个 SQL 连接池和与数据库的持久连接.
In traditional webservers you would have a SQL connection pool and persistent connection to the database.
但我正在考虑将我的整个应用程序创建为 Azure Functions.这些函数是否会在每次调用 SQL 服务器时创建一个新连接?
But I am thinking of creating my entire application as Azure Functions.Will the functions create a new connection the SQL server everytime its called upon?
推荐答案
Azure Functions 目前没有 SQL 作为输入或输出绑定的选项，因此您需要使用 SqlClient 类直接建立您的联系并发出您的查询.
Azure Functions doesn't currently have SQL as an option for an input or output binding, so you'd need to use the SqlClient classes directly to make your connections and issue your queries.
只要您遵循处置 SQL 连接的最佳实践(请参阅此示例:C# SQLConnection pooling)，你应该默认获得池化.
As long as you follow best practices of disposing your SQL connections (see this for example: C# SQLConnection pooling), you should get pooling by default.
