 Druid uses [log4j2](http://logging.apache.org/log4j/2.x/) for logging. Logging can be configured with a log4j2.xml file. Add the path to the directory containing the log4j2.xml file (e.g. the _common/ dir) to your classpath if you want to override default Druid log configuration. Note that this directory should be earlier in the classpath than the druid jars. The easiest way to do this is to prefix the classpath with the config dir.

+Apache Druid (incubating) can use Apache Cassandra as a deep storage mechanism. Segments and their metadata are stored in Cassandra in two tables:
 `index_storage` and `descriptor_storage`.  Underneath the hood, the Cassandra integration leverages Astyanax.  The
 index storage table is a [Chunked Object](https://github.com/Netflix/astyanax/wiki/Chunked-Object-Store) repository. It contains
 compressed segments for distribution to Historical processes.  Since segments can be large, the Chunked Object storage allows the integration to multi-thread
