| * Interface for defining a Drill format plugin. |
| * |
| * Format plugins are contained within storage plugins to describe particular |
| * data formats available in a given storage system. These formats are not |
| * necessarily tied to how the data is stored. One current use of this |
| * abstraction is describing different file formats like CSV and JSON that |
| * can be stored in a filesystem. Some storage systems like databases may only |
| * have a single format in which the data is actually stored. This interface |
| * enables flexibility for configuring the different data formats that will |
| * live under one storage system. The storage systems themselves are described |
| * in {@see StoragePluginConfig}s. |
