Fixes
- CPU load issue during head rotation. We addressed an issue where CPU load spiked due to aggressive index rebuilding on head rotation. The index updates have been redesigned to be lazy, meaning they now update upon request. This change has effectively reduced the CPU load.
- Decoupling head rotation and conversion timing. To further reduce system load, we have staggered the timing between head rotation and the conversion of the previous head into a historical block. This staggered approach helps to maintain smoother operations.
- Potential concurrency bug with SharedMemory. A bug involving potential concurrent access to SharedMemory has been fixed to ensure stable and safe operations across different processes.
