Hello Kylin Users, I found a similar mail thread of Dec. 2015 ( http://apache-kylin.74782.x6.nabble.com/Incremental-builds-assumptions-and-clarifications-td2736.html ). Can someone please confirm if this understanding is applicable for current version (v2.4) of Apache Kylin also?
Thank You, Shrikant Bang.
