Description
I see there are documents that explains how Kylin ingest hive tables and build cubes/cuboids using MR and/or spark but there is hardly anything about how it defines Metadata for cubes/segments, what are Segments, how it builds indexes (Dictionaries, Inverted index if any) and how that helps querying against cubes stored on hbase.
Other thing is how Kylin manages read-write isolation (read while write). Is it snapshot based or something that user needs to take care of?
