-<p class="content-header" style="margin-top:0.25em">What should I use Kylin for?</p>
-<p class="content-p">
-If you want to do multi-dimension analysis on large data sets (billion+ rows) with low query latency (sub-seconds), Kylin is a good option. Kylin also provides good integration with existing BI tools (e.g Tableau).
-</p>

-<hr/>
-
-<p class="content-header">Why existing SQL-on-Hadoop solutions fall short?</p>
-<p class="content-p">
-The existing SQL-on-Hadoop needs to scan partial or whole data set to answer a user query. Due to large data scan, many queries are very slow (minute+ latency).
-</p>
-<hr/>
-
-<p class="content-header">What is MOLAP/ROLAP?</p>
-<p class="content-p">
-MOLAP (Multi-dimensional OLAP) is to pre-compute data along different dimensions of interest and store resultant values in the cube. MOLAP is much faster but is inflexible.
-ROLAP (Relational-OLAP) is to use star or snow-flake schema to do runtime aggregation. ROLAP is flexible but much slower.
-</p>
-<hr/>
-
-<p class="content-header">How does Kylin support ROLAP/MOLAP?</p>
-<p class="content-p">
-Kylin builds data cube (MOLAP) from hive table (ROLAP) according to the metadata definition.
-If the query can be fulfilled by data cube, Kylin will route the query to data cube that is MOLAP.
-If the query can’t be fulfilled by data cube, Kylin will route the query to hive table that is ROLAP.
-Basically, you can think Kylin as HOLAP on top of MOLAP and ROLAP.
-</p>
-<hr/>
-<p class="content-header">What does a Kylin query look like?</p>
-<p class="content-p">
-Kylin supports join, projection, filter, aggregation, groups and sub-query. For example:
-<div align="left">
-
-<pre class="prettyprint" style="margin-top:1em;">select test_cal_dt.week_beg_dt, test_category.lv1_categ, test_category.lv2_categ, test_kylin_fact.format_name, test_sites.site_name, sum(test_kylin_fact.price) as total_price, count(*) as total_count from test_kylin_fact left join test_cal_dt on test_kylin_fact.cal_dt = test_cal_dt.cal_dt left join test_category on test_kylin_fact.leaf_categ_id = test_category.leaf_categ_id and test_kylin_fact.site_id = test_category.site_id left join test_sites on test_kylin_fact.site_id = test_sites.site_id where test_kylin_fact.seller_id = 123456 or test_kylin_fact.format_name = 'New' group by test_cal_dt.week_beg_dt, test_category.lv1_categ, test_category.lv2_categ, test_kylin_fact.format_name, test_sites.site_name</pre>
-</div>
-<hr/>
-
-<p class="content-header">What Hadoop components does it work with?</p>
-<p class="content-p">
-Kylin depends on HDFS, MapReduce, Hive and HBase.
-Hive and MapReduce is used for cube building. Hive is used for pre-join and MapReduce is used for pre-aggregation.
-HDFS is used to store intermediated files during cube building.
-HBase is used to store data cube and answer the query. HBase coprocessor is also used for query processing.
