Research direction
Investigate the sentinel datasource redis module in the Sentinel repository, specifically how it creates and closes Redis connections. Review the demo project at https://github.com/lvjianSingle/alibaba sentienl datasource redis bug to reproduce the connection leak. Examine configuration options like connection pool settings and the user's workaround of disabling the Sentinel endpoint to understand the root cause.
