In our project, we use node-cache as a cache layer.
We found an issue which looks like a API performance issue.
Our API responds status code '499' (client connection close, cause by our API response time is over client's limit), every 5minutes.
When we were looking for the reason, we found that we set node-cache TTL as 5minutes.
If node-cache block node's event loop when flush data, node server can't respond to API request during that time.
We are wondering if 'node-cache' block node event loop or not.

Thank you
