Hari Shreedharan commented on AVRO-1388:
----------------------------------------
It looks like there are a couple of methods which allow the user to set a raw
output stream, for the DataFileWriter to use. I don't know if it is reasonable
to assume that the OutputStream passed in is an instance of FileOutputStream.
Else we will need to do something like this:
{code}
if(out instanceof FileOutputStream) {
// we could do this check at the time of initialization and store a ref to
FileOutputStream directly to avoid this check on every fsync
((FileOutputStream)out).getFD().sync();
} else {
// throw or noop? Not sure throwing is really warranted here
}
{code}
> Avro container files should allow fsync-ing files to disk

> Another feature we require in Avro data files in addition to AVRO-1387 is
> that we be able to fsync the files to disk. Currently we cannot do this, but
> this can be achieved without API changes. If there are no objections, I will
> submit a patch
