zuston opened a new pull request, #2667: URL: https://github.com/apache/uniffle/pull/2667
### What changes were proposed in this pull request? Reconstruct the shuffle handle information if it hasn’t been updated. This means the latest shuffle handle data will no longer need to be transmitted through the RPC layer, reducing the load on the driver—especially when there are a large number of tasks. ### Why are the changes needed? For issue #2665: Once partition reassignment is enabled, the shuffle information is always retrieved when a task starts, which puts significant pressure on the Spark driver. Although in most cases the shuffle information remains unchanged, this behavior provides a natural point for optimization. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing tests could cover this PR's change. -- This is an automated message from the Apache Git Service.
