Well, we have 3 things it could mean: Cachegrand, Aerospike and dragonflydb.
Since the comment says "Trust me as a committer it smokes aerospike and dragonflydb." we can rule out aerospike and dragonflydb, which leaves us with "it" being Cachegrand. Ain't that deep.
Why would it be obvious we should implicitly trust (since all they said is "trust me") a committer to a project that their project is better (in any dimension) than competitors to their project?
That didn't make sense to me so I assumed they must not be a contributor to cachegrand.
