OpenPanel vs Apache SeaTunnel

The 2.3.13 release in March is by far the densest in this window: parallel splitting of large files for HDFS, local CSV/text/JSON and logical Parquet splits, CDC source schema evolution on the Flink engine, a checkpoint API with configurable minimum pause, and new connectors for DuckDB, Lance, AWS DSQL and HugeGraph. The releases before it were thinner — 2.3.12 and 2.3.11 are dominated by documentation, much of it Chinese translations of existing connector pages, and 2.3.9 and 2.3.8 are bug fix rollups.

Two things are happening at once. The engine is getting faster on the shapes that actually stall a pipeline — a single enormous file, a schema that changed under a running CDC job — and the connector catalogue keeps widening toward analytical and vector-adjacent stores rather than more transactional databases. But the cadence has stretched: releases used to land every two to three months, and nothing has shipped in nearly five.

Expect the split-and-parallel-read work started for files to extend to more source connectors, since it is the change with the broadest effect on throughput. The release gap is the open question — these entries show a lengthening interval without indicating whether a 2.4 line is being prepared behind it.
