<p>This tutorial demonstrates how to perform a batch file load, using Apache Druid (incubating)'s native batch ingestion.</p>
<p>For this tutorial, we'll assume you've already downloaded Druid as described in
the <a href="index.html">quickstart</a> using the <code>micro-quickstart</code> single-machine configuration and have it
running on your local machine. You don't need to have loaded any data yet.</p>
<p>A data load is initiated by submitting an <em>ingestion task</em> spec to the Druid Overlord. For this tutorial, we'll be loading the sample Wikipedia page edits data.</p>
<p>An ingestion spec can be written by hand or by using the &quot;Data loader&quot; that is built into the Druid console.
The data loader can help you build an ingestion spec by sampling your data and and iteratively configuring various ingestion parameters.
The data loader currently only supports native batch ingestion (support for streaming, including data stored in Apache Kafka and AWS Kinesis, is coming in future releases).
Streaming ingestion is only available through a written ingestion spec today.</p>
<p>We've included a sample of Wikipedia edits from September 12, 2015 to get you started.</p>

<p>Navigate to <a href="http://localhost:8888">localhost:8888</a> and click <code>Load data</code> in the console header.</p>
<p><img src="../assets/tutorial-batch-data-loader-01.png" alt="Data loader init" title="Data loader init"></p>
<p>Select <code>Local disk</code> and click <code>Connect data</code>.</p>
<p><img src="../assets/tutorial-batch-data-loader-02.png" alt="Data loader sample" title="Data loader sample"></p>
<p>Enter <code>quickstart/tutorial/</code> as the base directory and <code>wikiticker-2015-09-12-sampled.json.gz</code> as a filter.
The separation of base directory and <a href="https://commons.apache.org/proper/commons-io/apidocs/org/apache/commons/io/filefilter/WildcardFileFilter.html">wildcard file filter</a> is there if you need to ingest data from multiple files.</p>
<p>Click <code>Preview</code> and make sure that the data you are seeing is correct.</p>
<p>Once the data is located, you can click &quot;Next: Parse data&quot; to go to the next step.</p>
<p><img src="../assets/tutorial-batch-data-loader-03.png" alt="Data loader parse data" title="Data loader parse data"></p>
<p>The data loader will try to automatically determine the correct parser for the data.
In this case it will successfully determine <code>json</code>.
Feel free to play around with different parser options to get a preview of how Druid will parse your data.</p>
<p>With the <code>json</code> parser selected, click <code>Next: Parse time</code> to get to the step centered around determining your primary timestamp column.</p>
<p><img src="../assets/tutorial-batch-data-loader-04.png" alt="Data loader parse time" title="Data loader parse time"></p>
<p>Druid's architecture requires a primary timestamp column (internally stored in a column called <code>__time</code>).
If you do not have a timestamp in your data, select <code>Constant value</code>.
In our example, the data loader will determine that the <code>time</code> column in our raw data is the only candidate that can be used as the primary time column.</p>
<p>Click <code>Next: ...</code> twice to go past the <code>Transform</code> and <code>Filter</code> steps.
You do not need to enter anything in these steps as applying ingestion time transforms and filters are out of scope for this tutorial.</p>
<p><img src="../assets/tutorial-batch-data-loader-05.png" alt="Data loader schema" title="Data loader schema"></p>
<p>In the <code>Configure schema</code> step, you can configure which <a href="/docs/0.16.1-incubating/ingestion/index.html#dimensions">dimensions</a> and <a href="/docs/0.16.1-incubating/ingestion/index.html#metrics">metrics</a> will be ingested into Druid.
This is exactly what the data will appear like in Druid once it is ingested.
Since our dataset is very small, go ahead and turn off <a href="/docs/0.16.1-incubating/ingestion/index.html#rollup"><code>Rollup</code></a> by clicking on the switch and confirming the change.</p>
<p>Once you are satisfied with the schema, click <code>Next</code> to go to the <code>Partition</code> step where you can fine tune how the data will be partitioned into segments.</p>
<p><img src="../assets/tutorial-batch-data-loader-06.png" alt="Data loader partition" title="Data loader partition"></p>
<p>Here, you can adjust how the data will be split up into segments in Druid.
Since this is a small dataset, there are no adjustments that need to be made in this step.</p>
<p>Clicking past the <code>Tune</code> step, to get to the publish step.</p>
<p><img src="../assets/tutorial-batch-data-loader-07.png" alt="Data loader publish" title="Data loader publish"></p>
<p>The <code>Publish</code> step is where we can specify what the datasource name in Druid.
Let's name this datasource <code>wikipedia</code>.
Finally, click <code>Next</code> to review your spec.</p>
<p><img src="../assets/tutorial-batch-data-loader-08.png" alt="Data loader spec" title="Data loader spec"></p>
<p>This is the spec you have constructed.
Feel free to go back and make changes in previous steps to see how changes will update the spec.
Similarly, you can also edit the spec directly and see it reflected in the previous steps.</p>
<p>Once you are satisfied with the spec, click <code>Submit</code> and an ingestion task will be created.</p>
<p><img src="../assets/tutorial-batch-data-loader-09.png" alt="Tasks view" title="Tasks view"></p>
<p>You will be taken to the task view with the focus on the newly created task.
The task view is set to auto refresh, wait until your task succeeds.</p>
<p>When a tasks succeeds it means that it built one or more segments that will now be picked up by the data servers.</p>
<p>Navigate to the <code>Datasources</code> view from the header.</p>
<p><img src="../assets/tutorial-batch-data-loader-10.png" alt="Datasource view" title="Datasource view"></p>
<p>Wait until your datasource (<code>wikipedia</code>) appears.
This can take a few seconds as the segments are being loaded.</p>
<p>A datasource is queryable once you see a green (fully available) circle.
At this point, you can go to the <code>Query</code> view to run SQL queries against the datasource.</p>
<p><img src="../assets/tutorial-batch-data-loader-11.png" alt="Query view" title="Query view"></p>
<p>Run a <code>SELECT * FROM &quot;wikipedia&quot;</code> query to see your results.</p>
<p>Check out the <a href="/docs/0.16.1-incubating/tutorials/tutorial-query.html">query tutorial</a> to run some example queries on the newly loaded data.</p>

<p>Let's briefly discuss how we would've submitted the ingestion task without using the script. You do not need to run these commands.</p>
<p>To submit the task, POST it to Druid in a new terminal window from the apache-druid-0.16.1-incubating directory:</p>
<pre><code class="hljs css language-bash">curl -X <span class="hljs-string">'POST'</span> -H <span class="hljs-string">'Content-Type:application/json'</span> -d @quickstart/tutorial/wikipedia-index.json http://localhost:8081/druid/indexer/v1/task
</code></pre>
<p>Which will print the ID of the task if the submission was successful:</p>
<pre><code class="hljs css language-bash">{<span class="hljs-string">"task"</span>:<span class="hljs-string">"index_wikipedia_2018-06-09T21:30:32.802Z"</span>}
</code></pre>
<p>You can monitor the status of this task from the console as outlined above.</p>

<p>If you wish to go through any of the other ingestion tutorials, you will need to shut down the cluster and reset the cluster state by removing the contents of the <code>var</code> directory under the druid package, as the other tutorials will write to the same &quot;wikipedia&quot; datasource.</p>
