Kafka snappy compression

[小宇]

Hi, all
I'm working on snappy compression in our Node.js client (
https://github.com/SOHU-Co/kafka-node),but I found the offset of message
always 0 after snappy compression, for example: <Buffer 00 00 00 00 00 00
00 00 00 00 00 19 3e 69 5f c8 00 00 00 00 00 00 00 00 00 0b 7b 22 6f 6e 65
22 3a 22 31 22 7d>, I try to test it in kafka-cosole-producer.sh, but it
seems not support snappy. So I can't figure out what's wrong with my
client. Did anyone encounter the same problem?
Thanks.
