 Q1. What is the difference between TimeBasedRollingPolicy and SizeBasedTriggeringPolicy within Log4j ? Can we use both together and What would that mean ?Log4j
Ans. TimeBasedRollingPolicy enables rolling of logs based on the time / days whereas SizeBasedTriggeringPolicy enables rolling of logs based on size cap.

Yes we can use both together. In that case Logs will be rolled in case any of the condition is met i.e after the interval or if the size is reached.
