Description

Requesting an API lastSync() on DataFileWriter. It is useful to expose sync offsets during the process of writing an Avro file - Given sync info, it makes it easier to fetch a specific block and read if so desired, rather than having to read the whole file to locate contents of a record in a specific block.
