Warning Rate limit exceeded@WenyXu has exceeded the limit for the number of commits or files that can be reviewed per hour. Please wait 9 minutes and 8 seconds before requesting another review. How to resolve this issue?After the wait time has elapsed, a review can be triggered using the We recommend that you space out your commits to avoid hitting the rate limit. How do rate limits work?CodeRabbit enforces hourly rate limits for each developer per organization. Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout. Please see our FAQ for further information. WalkthroughThe changes primarily focus on enhancing fuzz testing functionalities in a database system. New targets for fuzz testing region migration and failover operations were added. Additionally, there’s a refactoring of the partitioning logic and introduction of utilities for region migration and procedure handling. The updates improve the testing of table partitioning, timestamp operations, and region management capabilities. Changes

To verify the correct usage of the
format_partitionfunction, we need to review the surrounding code where it is called. Let's extract and examine the context aroundif let Some(partition) = Self::format_partition(input)to ensure it is used correctly.
Let's adjust the search pattern to ensure it matches the correct line and re-run the script to extract the surrounding context for verification.
Let's perform a broader search to gather more context around the
format_partitionfunction calls to ensure we capture the relevant lines for verification.
