Konstantin Knauf commented on FLINK-30235:
------------------------------------------
I will mark this as "Not finished" for Flink 1.18 and remove the fixVersion
from the ticket as the feature freeze has passed. Thanks, Konstantin (one of
the release managers for Flink 1.18)
> Comprehensive benchmarks on changelog checkpointing

> Key: FLINK-30235
> URL: https://issues.apache.org/jira/browse/FLINK-30235
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing, Runtime / State Backends
> Reporter: Rui Xia
> Priority: Minor
> Labels: performance
>
> 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.
