Working with Drill
Connecting Drill to Data Sources
Drill serves as a query layer that connects to data sources through storage plugins. A storage plugin is a software module for connecting Drill to data sources. A storage plugin typically optimizes execution of Drill queries, provides the location of the data, and configures the workspace and file formats for reading data.
MapR Database Format Plugin for Drill
Drill supports access to MapR Database JSON and binary tables through the maprdb format plugin.

MapR Database Format Plugin for Drill

Drill supports access to MapR Database JSON and binary tables through the maprdb format plugin.

When you install Drill on MapR, Drill provides some options specific to the maprdb format plugin that you can change or configure. You can modify these options in the following places:
