我创建了一个数据迁移工具,它从旧版 SQL 数据库中读取数据,将其转换为更合理的数据,然后将其存储在 RavenDB 中。
当我尝试在单个 Raven 会话中写入 22500 个 1KB 对象时,我收到以下错误:
System.InvalidOperationException: Could not replicate POST operation to secondary node, failover behavior is: AllowReadsFromSecondaries
该消息表明 Master Raven 实例遇到致命错误,迁移工具故障转移到 Slave Slave Raven 实例并尝试对其进行写入。我不知道是为什么。
背景资料:
- .NET 4.0
- RavenDB #2025-Unstable(由于依赖 Json.NET,无法使用稳定版本)
- 使用 RavenDB 复制包(复制配置正确)
- 写入操作包含在 TransactionScope 中(迁移工具的其他地方使用单独的 Raven 会话进行写入)
- Windows 事件日志中没有错误
登录 Master Raven 实例包含以下错误:
System.Threading.ThreadAbortException: Thread was being aborted.

使用带有复制的事务时,每个会话的写入次数是否有上限?
这可能是使用不稳定构建的结果吗?
