snleee opened a new pull request #3913: Adding the support for sampling logs URL: https://github.com/apache/incubator-pinot/pull/3913 For high throughput use cases, logging becomes the bottleneck on both server and broker. "Category.callAppenders()" is using a synchronized block that all the worker threads can be stalled due to logging. Long term solution should be migration towards log4j2. As a short term fix, this pr adds the configuration for sampling logs.
