Expose sync points in DataFileReader
------------------------------------
Key: AVRO-652
URL: https://issues.apache.org/jira/browse/AVRO-652
Project: Avro
Issue Type: New Feature
Reporter: Stu Hood
Priority: Minor
DataFileReader.blockStart is hidden from the caller, but exposing it (as
readonly) would allow callers to discover sync points in a file by watching it
for changes.
seek(long) only takes an exact block boundary, while sync(long) moves to the
next block boundary. There does not appear to be a way to rediscover points
that you can seek() to, which would be very useful for building or recovering
an index for a file.
