ConfigService get_config Blocking Main Thread #241
Comments
I’m attempting to fix this issue.🙋 |
哇,非常好的提议。 |
但这里的重试主要是初始化链接时候的,应该不是 get_config 的 block。如果 block 住了是否 build() 没正常连上服务端? |
是的,因为可能会有网络原因无法连上服务器 |
设置最大连接次数能规避。 |
调用是这样的get_config-> |
可能希望单纯的希望当nacos server端网络连接不通的时候不必强依赖nacos也可以启动起来,因为这样强阻塞线程会让其他流程代码无法往下进行 |
看起来也非常奇怪,不过设置最大重试次数抛出 Error 对 sdk 来说没问题。 |
或许在FailoverConnection send_request里增加一个时间,在指定时间里没有执行成功,返回一次错误 |
我相信你设定 max_retry 肯定也会遇到这个问题,等你实践和觉得如何改造更佳。 使用 sdk 运行期因为远程 nacos-server 不可用而卡住线程这个确实在之前没有考虑到 |
When using the ConfigService get_config method in the main Tokio thread, the service fails to start if the connection address is not successful.
Although I have a local default configuration and prefer to fetch configurations from a remote source first, the system should fall back to the local configuration if the remote fetch fails.
However, ConfigService get_config blocks the main thread, preventing the service from proceeding.
This issue stems from NacosGrpcConnection’s poll_ready continuously retrying. I propose adding a configurable maximum retry limit, with a default value of None to retain the original logic.
Users could set this limit as needed to control the retry behavior.
