------------------------------------
Summary: Add Utility Functions for Compressed Files
Key: DRILL-7834
URL: https://issues.apache.org/jira/browse/DRILL-7834
Project: Apache Drill
Issue Type: Improvement
Components: Storage - Text & CSV
Affects Versions: 1.17.0
Reporter: Charles Givre
Assignee: Charles Givre
Fix For: 1.19.0
Some format plugins that use third party parsers throw errors when they receive
compressed input streams from Drill. This PR proposes to introduce three
utility functions to the DrillFileSystem:
# isCompressed(<path>): Returns true/false whether the input file is compressed
# getCodec(<path>): This method returns the codec of the file if any
# openDecompressedInputStream(<path>): Returns an InputStream that should be
readable by parsers that read raw bytes. This method converts the original
InputStream to a byte[] first, then returns that via a ByteArrayInputStream.
