我已实现了以下code写入到Azure数据库处理时,INSERT / UPDATE重试逻辑与指数退避。
I have implemented the following code for handling INSERT/UPDATE retry logic with exponential backoff when writing to an Azure Database.
static SqlConnection TryOpen(this SqlConnection connection) { int attempts = 0; while (attempts < 5) { try { if (attempts > 0) System.Threading.Thread.Sleep(((int)Math.Pow(3, attempts)) * 1000); connection.Open(); return connection; } catch { } attempts++; } throw new Exception("Unable to obtain a connection to SQL Server or SQL Azure."); }不过,我应该考虑应用重试逻辑我的数据库中读取呢?或将在SqlCommand.CommandTimeout()方法就足够了?我的大部分读取使用以下code被提起:
However should I consider applying retry logic for my database reads as well? Or would the SqlCommand.CommandTimeout() method suffice? Most of my reads are instituted using the following code:
Dim myDateAdapter As New SqlDataAdapter(mySqlCommand) Dim ds As New DataSet myDateAdapter.Fill(ds, "dtName")这是很难知道什么会发生在生产环境中使用Azure的,所以我想现在要做的尽可能多的缓解可能的排序瞬态错误的。
It's hard to know what sort of transient errors will occur in a production environment with Azure so I am trying to do as much mitigation as possible now.
推荐答案我觉得重试将要在你的一般的Windows Azure SQL数据库操作的一部分。
I think retries are going to be part of your Windows Azure SQL Database operations in general.
而不是实现自定义的解决方案,你看了的瞬态故障处理应用程序块由Microsoft模式与实践发表,专为SQL数据库?
Rather than implementing a custom solution, have you looked at the transient fault handling application block published by Microsoft Patterns and Practices, specifically for SQL Database?
