v0.4.1 -> v0.4.2

Summary

Trigger AOF compaction inline on writes when the inflation ratio (AOF lines / live keys) reaches 2x, with a minimum live-key threshold to avoid wasteful rewrites on small databases.

翻譯 在寫入路徑中依膨脹比（AOF 行數 / 活躍 key 數）達到 2 倍時自動觸發 compaction，並設定最小活躍 key 門檻避免小型資料庫進行無意義的重寫。

Changes

PERF

  • Track AOF line count per database and trigger compaction inline in addToAOF when aofLines >= live * 2 and live >= 1024, bounding AOF growth for long-running processes without requiring restart
  • Return line count from replayAOF to initialize the counter on lazy DB load
  • Reset aofLines to the post-compaction line count so the inflation baseline adapts as the working set grows
翻譯
  • 每個 database 追蹤 AOF 行數，在 addToAOF 中於 aofLines >= live * 2 且 live >= 1024 時直接觸發 compaction，讓長時間運行的 process 不需重啟即可控制 AOF 成長
  • replayAOF 回傳行數，用於 lazy DB 載入時初始化計數器
  • Compaction 完成後將 aofLines 重設為壓縮後的行數，讓膨脹比的基準隨工作集自適應調整
