[jira] [Created] (FLINK-30235) Comprehensive benchmarks on changelog checkpointing

Rui Xia created FLINK-30235:
-------------------------------

             Summary: 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


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.
