Quick Start with Sample Cube

Kylin provides a script for you to create a sample Cube; the script will also create five sample Hive tables:

1. Run ${KYLIN_HOME}/bin/sample.sh; Restart Kylin server to flush the caches;
2. Logon Kylin web with default user and password ADMIN/KYLIN, select project learn_kylin in the project dropdown list (left upper corner);
3. Select the sample Cube kylin_sales_cube, click "Actions" -> "Build", pick up a date later than 2014-01-01 (to cover all 10000 sample records);
4. Check the build progress in the "Monitor" tab, until 100%;
5. Execute SQLs in the "Insight" tab, for example:

select part_dt, sum(price) as total_sold, count(distinct seller_id) as sellers from kylin_sales group by part_dt order by part_dt

6.You can verify the query result and compare the response time with Hive;

Quick Start with Streaming Sample Cube

Kylin provides a script for streaming sample Cube also. This script will create a Kafka topic and send random messages constantly to the generated topic.

1. Export KAFKA_HOME first, and start Kylin.
2. Run ${KYLIN_HOME}/bin/sample.sh, it will generate Table DEFAULT.KYLIN_STREAMING_TABLE, Model kylin_streaming_model, Cube kylin_streaming_cube in learn_kylin project.
3. Run ${KYLIN_HOME}/bin/sample-streaming.sh, it will create Kafka Topic kylin_streaming_topic into the localhost:9092 broker. It also sends the random 100 messages into Kylin_streaming_topic per second.
4. Follow the standard Cube build process, and trigger the Cube kylin_streaming_cube build.
5. Check the build process in the "Monitor" tab, until at least one job is 100%.
6. Execute SQLs in the "Insight" tab, for example:

select count(*), HOUR_START from kylin_streaming_table group by HOUR_START

7.Verify the query result.
