Bryan Duxbury commented on THRIFT-110:
--------------------------------------

Ok. So I think I heard at least one vote of confidence for the protocol spec 
:). If no one else objects, I'm going to assume the spec is good enough for the 
moment, and then commit my java implementation.

> A more compact format

> Thrift is not very compact in writing out data as (say protobuf) . It does 
> not have the concept of variable length integers and various other 
> optimizations possible . In Solr we use a lot of such optimizations to make a 
> very compact payload. Thrift has a lot common with that format.
> It is all done in a single class
> http://svn.apache.org/viewvc/lucene/solr/trunk/src/java/org/apache/solr/common/util/NamedListCodec.java?revision=685640&view=markup
> The other optimizations include writing type/value  in same byte, very fast 
> writes of Strings, externalizable strings etc 
> We could use a thrift format for non-java clients and I would like to see it 
> as compact as the current java version
