Hari Shreedharan commented on FLUME-2352:
-----------------------------------------
Also, batch size of 200000 is not realistic. I'd like to see if batch sizes
between 1000 and 10000 show any difference with events of 500 bytes or so.
> HDFSCompressedDataStream should support appendBatch

> compressing events in batch is much more efficient than compressing one by
> one.
> I set hdfs.batchSize to 200000, when I use appendBatch() in BucketWriter, the
> append operation cost less than 1 seconds, while one by one might cost 10
> seconds.
