Description

Group commits are an optimization that trade off latency for higher throughput by deferring transaction acknowledgement and batching commit fsync() calls. For example, we can have a 5 ms fsync() period during which we let commits complete, but defer the fsync() and the acknowledgement until the end. This inflates commit latency, but allows more concurrency, increasing throughput.

Contributor guide

Research direction
Investigate the commit path in the source code, locate fsync() calls, and design a batching window to defer acknowledgements.
