Hi guys, Might be a immature question. I'm evaluating different sql front end codebases to refectory our SQL system on non-hadoop MapReduce. It is something similar to hadoop but API is not quite the same. I wonder if Optiq is suitable for it? I knew Cascading and Drill are using it. Are they using it for generate up to logical plan and write their own physical plan and operators? And is optiq provide plug-in style for that layer or we need to hack some code? Thanks. -- Best regards, Xiaoyu Ma
