Wes McKinney created ARROW-6180:
-----------------------------------
Summary: [C++] Create InputStream that references a read-only
segment of a RandomAccessFile
Key: ARROW-6180
URL: https://issues.apache.org/jira/browse/ARROW-6180
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Wes McKinney
If different threads wants to do buffered reads over different portions of a
file (and they are unable to create their own separate file handles), they may
clobber each other. I would propose creating an object that keeps the
RandomAccessFile internally and implements the InputStream API in a way that is
safe from other threads changing the file position
