[GitHub] [dubbo] hengyoush opened a new issue #8338: Optimize thread overhead of ExpiringCache.
hengyoush opened a new issue #8338:
URL: https://github.com/apache/dubbo/issues/8338
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 2.7.x
* Operating System version: xxx
* Java version: xxx
### Steps to reproduce this issue
I read the code about ExpiringCache. Currently, every method call starts a cleanup thread. Can we use a global thread pool (like JDK ScheduledExecutorService) for cleanup?
### Expected Result
### Actual Result
What actually happens?
If there is an exception, please attach the exception trace:

Just put your stack trace here!

AbstractCacheFactory internally caches Cache instances (such as ExpiringCache). Why do you miss the cache? Because I understand that only every time the createCache method is called will a new cleaning thread be started (for ExpiringCache)
