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.
