[jira] [Updated] (SPARK-25348) Data source for binary files

     [ https://issues.apache.org/jira/browse/SPARK-25348?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Xiangrui Meng updated SPARK-25348:
----------------------------------
    Description: 
It would be useful to have a data source implementation for binary files, which can be used to build features to load images, audio, and videos.

Microsoft has an implementation at [https://github.com/Azure/mmlspark/tree/master/src/io/binary.] It would be great if we can merge it into Spark main repo.

cc: [~mhamilton] and [~imatiach]

Proposed API:

Format name: "binary-file"

Schema:
* content: BinaryType
* status (following Hadoop FIleStatus):
 * path: StringType
 * modification_time: Timestamp
 * length: LongType (size limit 2GB)

Options:
* pathFilterRegex: only include files with path matching the regex pattern
* maxBytesPerPartition: The max total file size for each partition unless the partition only contains one file

We will also add `binaryFile` to `DataFrameReader` and `DataStreamReader` as convenience aliases.
