## Summary - Replace `IntList.size()` slab-iteration with a simple `totalSize` counter incremented on each `add()` - Eliminates O(slabs) overhead from dictionary encoding hot paths where `size()` is called frequently ## Details `IntList.size()` was iterating over all slabs to sum their lengths on every call. For delta encoding writers that check size thresholds frequently, this becomes O(slabs) per check. With a running counter it's O(1). The improvement is primarily relevant for large row groups where the number of slabs grows. All 576 parquet-column tests pass. -- This is an automated message from the Apache Git Service.
