> Changelog checkpointing is functionally usable right now. To make it as a
> productive feature, more comprehensive benchmarks are required. In this
> issue, I aim to answer the following two major concerns:
> * The expansion of full checkpoint size caused by changelog persistence;
> * The TPS regression caused by DTSL double-write;
> By the way, I will also present other metrics related to checkpointing.
