Release Process


  • A number of these steps still have been finalised/tested.
  • The use of needs to be replaced with svnpubsub and

The steps for Release Managers to create, vote and publish releases for Apache Cassandra.

While a committer can perform the initial steps of creating and calling a vote on a proposed release, only a PMC can complete the process of publishing and announcing the release.


Background docs

A debian based linux OS is required to run the release steps from. Debian-based distros provide the required RPM, dpkg and repository management tools.

Create and publish your GPG key

To create a GPG key, follow the guidelines. Include your public key in:

Publish your GPG key in a PGP key server, such as MIT Keyserver.

Create Release Artifacts

Any committer can perform the following steps to create and call a vote on a proposed release.

Check that no open jira tickets are urgent and currently being worked on. Also check with a PMC that there’s security vulnerabilities currently being worked on in private.

Perform the Release

Run the following commands to generate and upload release artifacts, to a nexus staging repository and distribution location:

cd ~/git
git clone
# Edit the variables at the top of `cassandra-builds/cassandra-release/`

# After cloning cassandra-builds repo, the is run from the actual cassandra git checkout,
# on the branch/commit that we wish to tag for the tentative release along with version number to tag.
# For example here <version-branch> might be `3.11` and <version> `3.11.3`
cd ~/git/cassandra/
git checkout cassandra-<version-branch>
../cassandra-builds/cassandra-release/ -v <version>

If successful, take note of the email text output which can be used in the next section “Call for a Vote”.

The script does not yet generate and upload the rpm distribution packages. To generate and upload them do:

cd ~/git/cassandra-build
docker build -f docker/centos7-image.docker docker/
docker run --rm -v `pwd`/dist:/dist `docker images -f label=org.cassandra.buildenv=centos -q` /home/build/ <version>-tentative
rpmsign --addsign dist/*.rpm

For more information on the above steps see the cassandra-builds documentation. The next step is to copy and commit these binaries to staging svnpubsub:

# FIXME the following commands is wrong while is still used instead of svnpubsub and
cd ~/git
svn co cassandra-dist-dev
mkdir cassandra-dist-dev/<version>
cp cassandra-build/dist/*.rpm cassandra-dist-dev/<version>/

svn add cassandra-dist-dev/<version>
svn ci cassandra-dist-dev/<version>

Call for a Vote

Fill out the following email template and send to the dev mailing list:

I propose the following artifacts for release as <version>.

sha1: <git-sha>



Staging repository:<nexus-id>/

The distribution packages are available here:${version}/

The vote will be open for 72 hours (longer if needed).

[1]: (CHANGES.txt);a=blob_plain;f=CHANGES.txt;hb=<version>-tentative
[2]: (NEWS.txt);a=blob_plain;f=NEWS.txt;hb=<version>-tentative

Post-vote operations

Any PMC can perform the following steps to formalize and publish a successfully voted release.

Publish Artifacts

Run the following commands to publish the voted release artifacts:

cd ~/git
git clone
# edit the variables at the top of ``

# After cloning cassandra-builds repo, `` is run from the actual cassandra git checkout,
# on the tentative release tag that we wish to tag for the final release version number tag.
cd ~/git/cassandra/
git checkout <version>-tentative
../cassandra-builds/cassandra-release/ -v <version> <staging_number>

If successful, take note of the email text output which can be used in the next section “Send Release Announcement”. The output will also list the next steps that are required. The first of these is to commit changes made to your checkout.

Promote Nexus Repository

  • Login to Nexus repository again.
  • Click on “Staging” and then on the repository with id “cassandra-staging”.
  • Find your closed staging repository, right click on it and choose “Promote”.
  • Select the “Releases” repository and click “Promote”.
  • Next click on “Repositories”, select the “Releases” repository and validate that your artifacts exist as you expect them.

Sign and Upload Distribution Packages to Bintray

Run the following command:

cd ~/git
# FIXME the next command is wrong while is used instead of svnpubsub and
svn mv<version>

# Create the yum metadata, sign the metadata, and sign some files within the signed repo metadata that the ASF sig tool errors out on
svn co cassandra-dist-redhat
cd cassandra-dist-redhat/<abbreviated-version>x/
createrepo .
gpg --detach-sign --armor repodata/repomd.xml
for f in `find repodata/ -name *.bz2`; do
  gpg --detach-sign --armor $f;

svn co<version> cassandra-dist-<version>
cd cassandra-dist-<version>
cassandra-build/cassandra-release/ cassandra-dist-<version>

Update and Publish Website

See `docs`_ for building and publishing the website. Also update the CQL doc if appropriate.

Release version in JIRA

Release the JIRA version.

  • In JIRA go to the version that you want to release and release it.
  • Create a new version, if it has not been done before.

Update to Next Development Version

Edit and commit build.xml so the base.version property points to the next version.

Send Release Announcement

Fill out the following email template and send to both user and dev mailing lists:

The Cassandra team is pleased to announce the release of Apache Cassandra version <version>.

when you need scalability and high availability without compromising
