Description

Java DataFileReader supports sync, seek, pastSync, etc. which allow parallel reads of files, and reasonably efficient "tailing" of files. It would be great if these were supported in C++ too.

Also, I think this would serve as a bit of a workaround for https://issues.apache.org/jira/browse/AVRO-2178 (stat a file & see if it has grown, sync/seek, read, repeat).
