<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class StorageLevel</h1><p class="nomargin-top"><span class="codelink"><a href="pyspark.storagelevel-pysrc.html#StorageLevel">source code</a></span></p>
<p>Flags for controlling the storage of an RDD. Each StorageLevel records
whether to use memory, whether to drop the RDD to disk if it falls out of
memory, whether to keep the data in memory in a serialized format, and
whether to replicate the RDD partitions on multiple nodes. Also contains
static constants for some commonly used storage levels, such as
MEMORY_ONLY.</p>
