Kafka server contains messages but consumer cannot receive any(producer used compression.type=snappy) -


i newbie in kafka.when using kafka 0.9.0, can set codec setting compression.type property of kafka producer.

suppose use snappy compression in producer, when consuming messages kafka using kafka-consumer, should decode data snappy or built-in feature of kafka consumer?

in office doc, not find property relates encoding in kafka consumer (it relates producer).

can clear this?

as mentioned in wiki page,there no need decompression logic on consumer side:

please have @ wiki page below:

https://cwiki.apache.org/confluence/display/kafka/compression

the data received consumer topic might contain both compressed uncompressed messages. consumer iterator transparently decompresses compressed data , returns uncompressed message.

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
