Any input as to the status of Trevni?
I'm researching column-oriented file formats that aren't tightly coupled to specific platforms - this precludes ORCFile, for example.
CIF seemed interesting, but IBM hasn't released the code. And Trevni seems to be a reasonable open source implementation of what they describe.
But I hadn't heard much about Trevni recently, or if anybody is using it for real work.
I see it mentioned in conjunction with Impala, but it sounds like that's on the roadmap versus being available yet.
For context, I'm looking into using a column store to speed up Cascading workflows.
