+
+<p>From Kylin 2.0 you can run UT(Unit test), environment cube provision and
IT(Integration test) separately. <br />
+Running <code class="highlighter-rouge">mvn verify
-Dhdp.version=2.2.4.2-2</code> (assume youâre on your sandbox) is all you
need to run a complete all the test suites.</p>
+
+<p>It will execute the following steps sequentially:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>1. Build Artifacts
+2. Run all UTs (takes few minutes)
+3. Provision cubes on the sandbox environment for IT uasge (takes 1~2 hours)
+4. Run all ITs (takes few tens of minutes)
+5. verify jar stuff
+</code></pre>
+</div>
+
+<p>If your code change is minor and it merely requires running UT, use: <br />
+<code class="highlighter-rouge">mvn test</code><br />
+If your sandbox is already provisioned and your code change will not affect
the result of sandbox provision, (and you donât want to wait hours of
provision) just run the following commands to separately run UT and IT: <br />
+<code class="highlighter-rouge">mvn test</code><br />
+<code class="highlighter-rouge">mvn failsafe:integration-test</code></p>
+
+<h3 id="cube-provision">Cube Provision</h3>
+
+<p>Environment cube provision is indeed running kylin cubing jobs to prepare
example cubes in the sandbox. These prepared cubes will be used by the ITs.
Currently provision step is bound with the maven pre-integration-test phase,
and it contains running BuildCubeWithEngine (HBase required),
BuildCubeWithStream(Kafka required) and BuildIIWithStream(Kafka Required). You
can run the mvn commands on you sandbox or your develop computer. For the
latter case you need to set kylin.job.run.as.remote.cmd=true in
<strong>$KYLIN_HOME/examples/test_case_data/sandbox/kylin.properties</strong>.
<br />
+Try appending <code class="highlighter-rouge">-DfastBuildMode=true</code> to
mvn verify command to speed up provision by skipping incremental cubing.</p>

<p>Kylin 1.x used to move as many as possible unit test cases from sandbox to
HBase mini cluster (not any more in 2.x), so that user can run tests easily in
local without a hadoop sandbox. Two maven profiles are created in the root
pom.xml, âdefaultâ and âsandboxâ. The default profile will startup a
HBase Mini Cluster to prepare the test data and run the unit tests (the test
cases that are not supported by Mini cluster have been added in the
âexcludeâ list). If you want to keep using Sandbox to run test, just run
<code class="highlighter-rouge">mvn test -P sandbox</code></p>

+ <p>Here are some basic
technical concepts used in Apache Kylin, please check them for your
reference.<br />
+For terminology in domain, please refer to: <a
href="terminology.md">Terminology</a></p>
+
+<h2 id="cube">CUBE</h2>
+<ul>
+ <li>
+ <p><strong>Table</strong> - This is definition of hive tables as source of
cubes, which must be synced before building cubes.<br />
+<img src="/images/docs/concepts/DataSource.png" alt="" /></p>
+ </li>
+ <li>
+ <p><strong>Data Model</strong> - This describes a <a
href="https://en.wikipedia.org/wiki/Star_schema";>STAR SCHEMA</a> data model,
which defines fact/lookup tables and filter condition.<br />
+<img src="/images/docs/concepts/DataModel.png" alt="" /></p>
+ </li>
+ <li>
+ <p><strong>Cube Descriptor</strong> - This describes definition and
settings for a cube instance, defining which data model to use, what dimensions
and measures to have, how to partition to segments and how to handle auto-merge
etc.<br />
+<img src="/images/docs/concepts/CubeDesc.png" alt="" /></p>
+ </li>
+ <li>
+ <p><strong>Cube Instance</strong> - This is instance of cube, built from
one cube descriptor, and consist of one or more cube segments according
partition settings.<br />
+<img src="/images/docs/concepts/CubeInstance.png" alt="" /></p>
+ </li>
+ <li>
+ <p><strong>Partition</strong> - User can define a DATE/STRING column as
partition column on cube descriptor, to separate one cube into several segments
with different date periods.<br />
+<img src="/images/docs/concepts/Partition.png" alt="" /></p>
+ </li>
+ <li>
+ <p><strong>Cube Segment</strong> - This is actual carrier of cube data,
and maps to a HTable in HBase. One building job creates one new segment for the
cube instance. Once data change on specified data period, we can refresh
related segments to avoid rebuilding whole cube.<br />
+<img src="/images/docs/concepts/CubeSegment.png" alt="" /></p>
+ </li>
+ <li>
+ <p><strong>Aggregation Group</strong> - Each aggregation group is subset
of dimensions, and build cuboid with combinations inside. It aims at pruning
for optimization.<br />
+<img src="/images/docs/concepts/AggregationGroup.png" alt="" /></p>
+ </li>
+</ul>
+
+<h2 id="dimension--measure">DIMENSION & MEASURE</h2>
+<ul>
+ <li><strong>Mandotary</strong> - This dimension type is used for cuboid
pruning, if a dimension is specified as âmandatoryâ, then those
combinations without such dimension are pruned.</li>
+ <li><strong>Hierarchy</strong> - This dimension type is used for cuboid
pruning, if dimension A,B,C forms a âhierarchyâ relation, then only
combinations with A, AB or ABC shall be remained.</li>
+ <li>
+ <p><strong>Derived</strong> - On lookup tables, some dimensions could be
generated from its PK, so thereâs specific mapping between them and FK from
fact table. So those dimensions are DERIVED and donât participate in cuboid
generation.<br />
+<img src="/images/docs/concepts/Dimension.png" alt="" /></p>
+ </li>
+ <li><strong>Count Distinct(HyperLogLog)</strong> - Immediate COUNT DISTINCT
is hard to calculate, a approximate algorithm - <a
href="https://en.wikipedia.org/wiki/HyperLogLog";>HyperLogLog</a> is introduced,
and keep error rate in a lower level.</li>
+ <li><strong>Count Distinct(Precise)</strong> - Precise COUNT DISTINCT will
be pre-calculated basing on RoaringBitmap, currently only int or bigint are
supported.</li>
+ <li><strong>Top N</strong> - (Will release in 2.x) For example, with this
measure type, user can easily get specified numbers of top sellers/buyers etc.
<br />
+<img src="/images/docs/concepts/Measure.png" alt="" /></li>
+</ul>
+
+<h2 id="cube-actions">CUBE ACTIONS</h2>
+<ul>
+ <li><strong>BUILD</strong> - Given an interval of partition column, this
action is to build a new cube segment.</li>
+ <li><strong>REFRESH</strong> - This action will rebuilt cube segment in some
partition period, which is used in case of source table increasing.</li>
+ <li><strong>MERGE</strong> - This action will merge multiple continuous cube
segments into single one. This can be automated with auto-merge settings in
cube descriptor.</li>
+ <li><strong>PURGE</strong> - Clear segments under a cube instance. This will
only update metadata, and wonât delete cube data from HBase.<br />
+<img src="/images/docs/concepts/CubeAction.png" alt="" /></li>
+</ul>
+
+<h2 id="job-status">JOB STATUS</h2>
+<ul>
+ <li><strong>NEW</strong> - This denotes one job has been just created.</li>
+ <li><strong>PENDING</strong> - This denotes one job is paused by job
scheduler and waiting for resources.</li>
+ <li><strong>RUNNING</strong> - This denotes one job is running in
progress.</li>
+ <li><strong>FINISHED</strong> - This denotes one job is successfully
finished.</li>
+ <li><strong>ERROR</strong> - This denotes one job is aborted with
errors.</li>
+ <li><strong>DISCARDED</strong> - This denotes one job is cancelled by end
users.<br />
+<img src="/images/docs/concepts/Job.png" alt="" /></li>
+</ul>
+
+<h2 id="job-action">JOB ACTION</h2>
+<ul>
+ <li><strong>RESUME</strong> - Once a job in ERROR status, this action will
try to restore it from latest successful point.</li>
+ <li><strong>DISCARD</strong> - No matter status of a job is, user can end it
and release resources with DISCARD action.<br />
+<img src="/images/docs/concepts/JobAction.png" alt="" /></li>
