Try a range from smaller block sizes (4k) and up. 256K is a larger block size than many compression codecs are sensitive to.
Also for reference, try it with the deflate codec at a couple different compression levels -- 1, 3, 5, and 7 should show a trend with respect to block size. As the compression level increases, the compressor can take advantage of larger blocks. In the deflate/gzip case that I have explored heavily, the effectiveness of the block size also varies significantly depending on the characteristics of the data being compressed. (note: gzip uses deflate compression) On 4/18/12 1:33 PM, "snikhil0" <[email protected]> wrote: >I had tried the sync Interval as well and I get the same results: meaning >no >change in final avro data file. > >Nikhil > >-- >View this message in context: >http://apache-avro.679487.n3.nabble.com/Avro-Snappy-changing-blocksize-of- >snappy-compression-tp3920732p3921256.html >Sent from the Avro - Users mailing list archive at Nabble.com.
