Thanks. ---------- Forwarded message ---------- From: [email protected] <[email protected]> Date: Wed, Jun 24, 2015 at 2:46 PM Subject: Several questions about Kylin To: lukehan <[email protected]> Hi~ Recently, I've learned something about OLAP and Data Warehouse, I find that using Apache Kylin is pretty efficient to solve many OLAP problems especially in processing large amount od data. However ,the question is, I'm new to this area and I've tried to read your source code, but I'm still feel confused about some details of kylin. For example, how did kylin transform the intermediate tables into HBase tables ? How did kylin store data in HBase, rowkey & value encoding/decoding ?(using optiq or what) Ah,thank you so much if you could give me some instructions or something else so that I can know more about kylin in detail. Looking forward to hearing from you! Sincerely ^_^ ------------------------------ [email protected]
