-        <title>Streaming cubing (Prototype)</title>
-        <description>&lt;p&gt;One of the most important features in v1.5 is 
streaming cubing which enables OLAP analysis on streaming data. Streaming 
cubing delivers faster insights on the data to help more promptly business 
decisions. Even though there are already many real time analysis tools in open 
source community, Kylin Streaming cubing still differs from them in multiple 
angles:&lt;/p&gt;
-
-&lt;p&gt;Firstly, Kylin Streaming Cubing aligns with Kylin traditional cubing 
to provided unified, ANSI SQL interface. Actually Kylin Streaming shares the 
storage engine and query engine with traditional Kylin cubes, so in theory all 
of the optimization techniques to save storage and speed up query performance 
can also be applied on streaming cubes. Besides, all the supported 
aggregations/filters/UDFs still work for streaming cubes. By unifying the 
storage engine and query engine we also get freed from double amount of 
maintaince work.&lt;/p&gt;
-
-&lt;p&gt;Secondly, Kylin Streaming Cubing does not require large amount of 
memory to store real time data, nor does it attempts to provide truly “real 
time” analysis. By our customer survey we found that minutes of visualization 
latency is acceptable for OLAP analysts. So our streaming cubing adopts the 
micro batch approach. Incoming streaming data are partitioned into different 
time windows and we build a micro batch for each time window. The cube output 
for each micro batch is directly saved to HBase. The query engine goes to HBase 
for data retrieving instead of the data ingestion server. The benefit of such 
design is that we don’t have to maintain large amount of in-memory index 
which could easily require tens of gigabytes of memory. In the future Kylin 
might need to consider truly “real time” support, too.&lt;/p&gt;
-
-&lt;p&gt;Thirdly, Kylin Streaming Cubing data will be persistent and gradually 
be converted to traditional cubes, thus customers can still query “cold 
data” without any compromise on performance. As discussed above the output of 
streaming cubing is directly saved to HBase as a new segment. The traditional 
job engine will be notified of the new segment and take over to schedule merge 
jobs when then segments accumulates. Day after day the segments of the 
streaming cube got merged and become a very large traditional cube.&lt;/p&gt;
-
-&lt;p&gt;&lt;img src=&quot;/images/develop/streaming.png&quot; alt=&quot;Kylin 
Streaming Framework Architecture&quot; /&gt;&lt;/p&gt;
-
-&lt;p&gt;With the major difference in mind we will introduce the modules for 
Kylin Streaming cubing. Kylin Streaming cubing consist of three major 
parts:&lt;/p&gt;
-
-&lt;ul&gt;
-  &lt;li&gt;Streaming Input to retrieve data from a replayable data queue 
(currently it is Kafka) within given time window. Streaming Input is also 
responsible for primary data cleaning and normalization. By default Kylin 
Streaming provides a default implementation to parse the messages from the 
source queue. Customers can choose to configure the parser or provide a brand 
new one based on their requirements.&lt;/li&gt;
-  &lt;li&gt;Streaming Batch Ingestion to ingest the incoming data batch and 
transform it into a micro cube. Thanks to the latest Kylin In-memory cubing 
technology, this step is now times faster and space-saving than previous. The 
micro cube is directly saved to HBase.&lt;/li&gt;
-  &lt;li&gt;Job Scheduling Module to trigger Streaming Batch Ingestion. Kylin 
does not put too much efforts in job scheduling, streaming cubing is not a 
exception. Currently we provided a simple implementation based on Linux 
Crontab.&lt;/li&gt;
-&lt;/ul&gt;
-
-&lt;p&gt;We’ll publish more detailed documents on how to use Kylin Streaming 
soon. Please stay tuned.&lt;/p&gt;
