Apache SkyWalking vs Apache SeaTunnel: at a glance
What is Apache SkyWalking?
SkyWalking is rebuilding its own foundations — its own database, its own runtime, and now GenAI traces
Apache SkyWalking ships roughly one major a year. 10.4.0 added GenAI observability, replaced the Groovy-dependent runtime with a new OAL V2 engine, and became compatible with Grafana Tempo. Before it, 10.3.0 landed a new trace model in BanyanDB, and 10.2.0 removed the H2 storage option permanently while deepening BanyanDB support.
What is Apache SeaTunnel?
SeaTunnel can finally split one large file across readers — and hasn't shipped since March.
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.

SkyWalking is rebuilding its own foundations — its own database, its own runtime, and now GenAI traces
◆ Current state
Apache SkyWalking ships roughly one major a year. 10.4.0 added GenAI observability, replaced the Groovy-dependent runtime with a new OAL V2 engine, and became compatible with Grafana Tempo. Before it, 10.3.0 landed a new trace model in BanyanDB, and 10.2.0 removed the H2 storage option permanently while deepening BanyanDB support.
◆ Where it's heading
Two rewrites are running at once. Storage is consolidating onto BanyanDB, SkyWalking's purpose-built database, with alternatives being removed rather than deprecated. The query and aggregation layer is moving off Groovy onto a typed, immutable OAL V2 engine with real error locations. GenAI observability arriving on top of that suggests the foundations work was clearing room for new telemetry types.
◆ Prediction
Expect the next major to extend GenAI observability and continue narrowing supported storage backends toward BanyanDB, with further OAL V2 migration on the way.

SeaTunnel can finally split one large file across readers — and hasn't shipped since March.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
