Hi All Now if I want to build a OLAP platform to analyze our huge data, the first impression is using Hive，but it can not match our real-time query needs. Then I found lots of companies used ES to build their OLAP engine before like tencent’s Hermes. So I want to know that what’s the difference between ES and Apache Kylin from different dimensions like filter, aggregation queries or etc.
* Performance * Flexible queries * Data Model * BI integration * … After Kylin release latest architecture that can support different storage engine, I found that Kylin will support ES[1] as it’s backend storage engine. So I think ES is ROLAP engine that lots of people use ES as NoSQL DB and Kylin is a MOLAP engine. I would love to hear some feedback for my confusions. Thanks.
