We have framework for analysis data with the help of cube design for OLAP and warehouse that has ETL connections, all of them are in sqlServer structure and SSRS(SQL Server Reporting Services). Some of our reports take a lot of time to come to a conclusion, we decided to migrate to Hadoop ecosystem. is Apache Kylin a good alternative for this framework ?
First of all, I would compare SQL Server Analysis Services with Kylin and not Reporting Services as Reporting Services is closer to front-end system.
Based on my experience, with SQL Server SSAS you can do a lot of things that you can not do with Kylin.
On the other side, Kylin is a distributed system compared with Microsoft SQL Server with Analysis Services, where you can do some finetuning but it will never be a true distributed system.
