+<h2>monotonically_increasing_id</h2>
+
+<h3>Description</h3>
+
+<p>Return a column that generates monotonically increasing 64-bit integers.
+</p>
+
+
+<h3>Usage</h3>
+
+<pre>
+monotonically_increasing_id(x = "missing")
+
+## S4 method for signature 'missing'
+monotonically_increasing_id()
+</pre>
+

+<h3>Arguments</h3>

+<table summary="R argblock">
+<tr valign="top"><td><code>x</code></td>
+<td>
+<p>empty. Should be used with no argument.</p>
+</td></tr>
+</table>
+
+
+<h3>Details</h3>
+
+<p>The generated ID is guaranteed to be monotonically increasing and unique, but not consecutive.
+The current implementation puts the partition ID in the upper 31 bits, and the record number
+within each partition in the lower 33 bits. The assumption is that the SparkDataFrame has
+less than 1 billion partitions, and each partition has less than 8 billion records.
+</p>
+<p>As an example, consider a SparkDataFrame with two partitions, each with 3 records.
+This expression would return the following IDs:
+0, 1, 2, 8589934592 (1L &lt;&lt; 33), 8589934593, 8589934594.
+</p>
+<p>This is equivalent to the MONOTONICALLY_INCREASING_ID function in SQL.
