Technical Highlights

OLAP and OLAP Cube
Online analytical processing, or OLAP,
is an approach to answering multi-
dimensional analytical (MDA) queries
swiftly in computing. – Wikipedia
Basic operations
– Roll-up
– Drill-down
– Slice and dice
– Pivot
OLAP cube is a data
structure optimized for
very quick data analysis.

Multidimensional Schema
Apach Kylin supports Star-Schema, Snowflake-Schema

Persistent the cube in HBase
Relational to Key Value store

17. © Kyligence Inc. 2018.
How to query the cube
Translate cube query into HBase table scan
– Columns, Group by → Cuboid ID
– Filters -> Scan Range (Row Key)
– Aggregations -> Measure Columns (Row Values)
Scan HBase table and translate HBase result into cube result
– HBase Result (key + value) -> Cube Result (dimensions +
measures)
No Hive touch, no MapReduce job in the query time

Use Case: Online Shopping Reporting
https://techblog.yahoo.co.jp/oss/apache-kylin/
▪ Our reporting system used Impala as a backend database
previously.
- It took a long time (about 60 sec) to show Web UI.
▪ In order to lower the latency, we moved to Apache Kylin.
- Average latency < 1sec for most cases
▪ Thanks to low latency with Kylin, we become possible
to focus on adding functions for users.
▪ We provide a reporting system that show statistics
for store owners.
- e. g. impressions, clicks and sales.
