LeetCode Rewind analytics features to leverage StarRocks

StarRocks announced that LeetCode, an online coding platform will leverage the StarRocks platform to power LeetCode Rewind. The revolutionary new feature allows users to replay past attempts, analyze code execution step-by-step, and gain deeper insights into their strengths and weaknesses by tracking progress over time.

Delivering this interactive experience at scale presented a significant technical challenge according to LeetCode which needed a data platform that could handle a massive influx of historical code submissions while providing instant responses to millions of users simultaneously.
