+          <p>Implement the Drill interface appropriate for the type of function that you
+want to develop. Each interface provides a set of required holders where you
+input data types that your function uses and required methods that Drill calls
+to perform your function’s operations.</p>
+
+<h2 id="simple-function-interface">Simple Function Interface</h2>
+
+<p>When you develop a simple function, you implement the <code>DrillSimpleFunc</code> interface. The name of the function is determined by the characters that you assign to the name variable. For example, the name for the following simple function is <code>myaddints</code>:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">@FunctionTemplate(name = &quot;myaddints&quot;, scope = FunctionScope.SIMPLE, nulls = NullHandling.NULL_IF_NULL)
+public static class Add1 implements DrillSimpleFunc{
+</code></pre></div>
+<p>The <code>nulls = NullHandling.NULL_IF_NULL</code> variable tells Drill to return NULL values as NULL. For most scenarios, this setting should suffice. If you want to change how Drill handles NULL values, you can change the setting to <code>nulls = NullHandling.INTERNAL</code>.</p>
+
+<p>The simple function interface includes holders where you indicate the data types that your function can process.</p>
+
+<p>The following table provides a list of the holders and their descriptions, with examples: </p>
+
+<table><tbody><tr><th ><strong>Holder</strong></th><th ><strong>Description</strong></th><th ><strong>Example</strong></th></tr><tr><td valign="top" ><code>@Param</code></td><td valign="top" >Indicates the data type that the function processes as input and determines the number of parameters that your function accepts within the query.</td><td valign="top" ><code>@Param BigIntHolder input1;</code><br /><code>@Param BigIntHolder input2;</code></td></tr><tr><td valign="top" ><code>@Output</code></td><td valign="top" >Indicates the data type that the processing returns.</td><td valign="top" ><code>@Output BigIntHolder out;</code> </td></tr></tbody></table>
+
+<p>The simple function interface also includes two required methods that Drill calls when processing a query with the function.</p>
+
+<p>The following table lists the required methods:</p>
+
+<table><tbody><tr><th><strong>Method</strong></th><th ><strong>Description</strong></th></tr><tr><td valign="top" ><code>setup()</code></td><td valign="top" >Performs the initialization and processing that Drill only performs once.</td></tr><tr><td valign="top" ><code>eval()</code></td><td valign="top" >Contains the code that tells Drill what operations to perform on columns of data. You add your custom code to this method.</td></tr></tbody></table>
+
+<h2 id="example">Example</h2>
+
+<p>The following example shows the program created for the <code>myaddints</code> function:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">package org.apache.drill.udfs;

+    public void setup(RecordBatch b){}
+
+    public void eval(){
+      out.value = input1.value + input2.value;
+    }
+  }
+</code></pre></div>
+<h2 id="aggregate-function-interface">Aggregate Function Interface</h2>
+
+<p>When you develop an aggregate function, you implement the <code>DrillAggFunc</code> interface. The name of the function is determined by the characters that you assign to the name variable. For example, the name for the following aggregate function is <code>mysecondmin</code>:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">@FunctionTemplate(name = &quot;mysecondmin&quot;, scope = FunctionTemplate.FunctionScope.POINT_AGGREGATE)
+public static class MySecondMin implements DrillAggFunc {
+</code></pre></div>
+<p>The aggregate function interface includes holders where you indicate the data types that your function can process.</p>
+
+<p>The following table provides a list of the holders and their descriptions, with examples: </p>
+
+<table ><tbody><tr><th ><strong>Holder</strong></th><th ><strong>Description</strong></th><th ><strong>Example</strong></th></tr><tr><td valign="top" ><code>@Param</code></td><td valign="top" >Indicates the data type that the function processes as input and determines the number of parameters that your function accepts within the query.</td><td valign="top" ><code>@Param BigIntHolder in;</code></td></tr><tr><td valign="top" ><code>@Workspace</code></td><td valign="top" >Indicates the data type used to store intermediate data during processing.</td><td valign="top" ><code>@Workspace BigIntHolder min;</code><br><code >@Workspace BigIntHolder secondMin;</code></td></tr><tr><td valign="top" ><code>@Output</code></td><td valign="top" >Indicates the data type that the processing returns.</td><td valign="top" ><code>@Output BigIntHolder out;</code></td></tr></tbody></table>
+
+<p>The aggregate function interface also includes four required methods that Drill calls when processing a query with the function.</p>
+
+<p>The following table lists the required methods:</p>
+
+<table><tbody><tr><th ><strong>Method</strong></th><th ><strong>Description</strong></th></tr><tr><td valign="top" ><code>setup()</code></td><td valign="top" >Performs the initialization and processing that Drill only performs once.</td></tr><tr><td valign="top" ><code>add()</code></td><td valign="top" >Processes each and every record. It applies the function to each value in a column that Drill processes.</td></tr><tr><td valign="top" ><code>output()</code></td><td valign="top" >Returns the final result of the aggregate function; the computed value of the processing applied by the Add method. This is the last method that Drill calls. Drill calls this one time after processing all the records.</td></tr><tr><td valign="top" ><code>reset()</code></td><td valign="top" >You provide the code in this method that determines the action Drill takes when data types in a column change from one type to another, for example from int to float. Before processing schema-less data, Drill scans the d
 ata and implicitly tries to identify the data type associated with each column. If Drill cannot identify a schema associated with each column, Drill processes a column assuming that the column contains a certain data type. If Drill encounters another data type in the column, Drill calls the reset method to determine how to handle the scenario.</td></tr></tbody></table>
