Trafodion

20 Sep 2017

Apache Trafodion is a webscale SQL-on-Hadoop solution enabling  transactional
or operational workloads on Hadoop. Trafodion builds on the scalability,
elasticity, and flexibility of Hadoop. Trafodion extends Hadoop to provide
guaranteed transactional integrity, enabling new kinds of big data
applications to run on Hadoop.

Trafodion has been incubating since 2015-05-24.

Three most important issues to address in the move towards graduation:

 1. Develop the community and continue to grow the diversity.
 2. Continue the momentum and become more integrated with the
    rest of the Apache community.
 3. Continue to create software releases.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?

 * Two of our three remaining mentors, Devaraj Das and Enis Söztutar, resigned
   on July 21.

How has the community developed since the last report?

 * Participation in the project remains healthy, with the usual small dip
   due to the summer vacation season:
   - ML postings: 106 user, 273 dev, 389 coderev, 734 issues, 341 commits
   - Twitter: 221 followers, 72 tweets, 67 likes
 * We are working towards our next release, 2.2. Ming Liu is the Release Manager.
 * Discussion regarding readiness to graduate continues. Diversity continues
   to grow.

How has the project developed since the last report?

 * 162 commits from 18 contributors.
 * 100 JIRAs filed and 63 resolved.

How would you assess the podling's maturity? Please feel free to add your own
commentary.
