> Image Metadata Format Plugin
> ----------------------------
>
> Key: DRILL-4364
> URL: https://issues.apache.org/jira/browse/DRILL-4364
> Project: Apache Drill
> Issue Type: New Feature
> Components: Storage - Other
> Reporter: Akihiko Kusanagi
>
> Support querying of metadata in various image formats. This plugin leverages
> [metadata-extractor|https://github.com/drewnoakes/metadata-extractor]. This
> plugin is especially useful when querying on a large number of image files
> stored in a distributed file system without building metadata repository in
> advance.
> This plugin supports the following file formats.
> * JPEG, TIFF, WebP, PSD, PNG, BMP, GIF, ICO, PCX
> * Camera Raw: NEF (Nikon), CR2 (Canon), ORF (Olympus), ARW (Sony), RW2
> (Panasonic), RWL (Leica), SRW (Samsung)
> This plugin enables to read the following metadata.
> * Exif, IPTC, XMP, JFIF / JFXX, ICC Profiles, Photoshop fields, WebP
> properties, PNG properties, BMP properties, GIF properties, ICO properties,
> PCX properties
> Since each type of metadata has a different set of fields, the plugin returns
> a set of commonly-used fields such as the image width, height and bits per
> pixels for ease of use.
> *Examples:*
> Querying on a JPEG file with the property descriptive: true
> {noformat}
> 0: jdbc:drill:zk=local> select * from dfs.`4349313028_f69ffa0257_o.jpg`;
