Wes McKinney updated ARROW-6180: -------------------------------- Summary: [C++] Create InputStream that references a segment of a RandomAccessFile (was: [C++] Create InputStream that references a read-only segment of a RandomAccessFile) > [C++] Create InputStream that references a 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 > Priority: Major > > 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 -- This message was sent by Atlassian JIRA (v7.6.14#76016)
