+title: "MapR-DB Format"
+date:
+parent: "Connect a Data Source"
+---
+
+The MapR-DB format is not included in the Apache Drill release. Drill includes a [maprdb
format](http://maprdocs.mapr.com/51/index.html#Drill/UsingMapRdbFormat.html) for MapR-DB that
is defined within the default dfs storage plugin configuration when you install Drill from
the mapr-drill package on a MapR node. The maprdb format improves the estimated number of
rows that Drill uses to plan a query. It also enables you to query tables like you would query
files in a file system because MapR-DB and MapR-FS share the same namespace.
+
+You can query tables stored across multiple directories. You do not need to create a table
mapping to a directory before you query a table in the directory. You can select from any
table in any directory the same way you would select from files in MapR-FS, using the same
syntax.
+
+Instead of including the name of a file, you include the table name in the query. The userid
running the query must have read permission to access the MapR table.
+
+**Example**
+
+ SELECT * FROM mfs.`/users/max/mytable`;
+
+The following image shows a portion of the dfs configuration with the maprdb format:
