Subject [jira] [Commented] (LEGAL-303) RocksDB Integrations
Date Fri, 09 Jun 2017 01:06:18 GMT

    [ https://issues.apache.org/jira/browse/LEGAL-303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16043757#comment-16043757

Yonik Seeley commented on LEGAL-303:
------------------------------------

Unofficially, I concur.  The patent retaliation clause seems to go well beyond our ASL and
is thus seems unsuitable for a dependency.
As for a plugin, to be on the safe side it seems like any RocksDB implementation of a Cassandra
storage plugin (which presumably would need to include some RocksDB code) should be outside
of the Cassandra project.

Facebook's messaging: https://code.facebook.com/posts/1639473982937255/updating-our-open-source-patent-grant/
Some other opinions: https://news.ycombinator.com/item?id=12692552

Of course, if you look at https://github.com/facebook/rocksdb/blob/master/USERS.md 
it seems that both Apache Flink and Apache Samza maintain RocksDB storage plugins (and I verified
quickly by looking at their code repos).... so this question should probably be cleared up
at an ASF level?

> Hi Legal,
> There's a hypothetical question on the Apache Cassandra mailing list about potentially
expanding Cassandra's storage to be pluggable, specifically using RocksDB.
> RocksDB has a 3 clause BSD license (
> https://github.com/facebook/rocksdb/blob/master/LICENSE ), and a patent
> grant ( https://github.com/facebook/rocksdb/blob/master/PATENTS )
> I know the 3 clause BSD license is fine, but is the wording of the patent grant problematic?
