Previously, PathDB used a single buffer to aggregate database writes, which needed to be flushed atomically. However, flushing large amounts of data (e.g., 256MB) caused significant overhead, often blocking the system for around 3 seconds during the flush. To mitigate this overhead and reduce performance spikes, a double-buffer mechanism is introduced. When the active buffer fills up, it is marked as frozen and a background flushing process is triggered. Meanwhile, a new buffer is allocated for incoming writes, allowing operations to continue uninterrupted. This approach reduces system blocking times and provides flexibility in adjusting buffer parameters for improved performance. |
