Overview
This is an assessment of the SeaTunnel podling’s maturity, meant to help inform the decision (of the mentors, community, Incubator PMC and ASF Board of Directors) to graduate it as a top-level Apache project.
It is based on the ASF project maturity model at https://community.apache.org/apache-way/apache-project-maturity-model.html

...
YES. All releases are signed, and the KEYS file is provided on dist.apache.org.
...

...
YES.
Convenience binaries are distributed via Maven Central Repository and via dist.apache.org at the same time.

RE50
...
The release process is documented and repeatable to the extent that someone new to the project is able to independently generate the complete set of artifacts required for a release.
...
YES. Release guide is available describing the entire process. The SeaTunnel releases have been performed by more than four different release manager.s
...
Quality
