Bryan Duxbury updated THRIFT-110:
---------------------------------

    Attachment: thrift-110.patch

Here's a patch for TCompactProtocol in Java. It deviates slightly from the spec I attached previously, so I'll have to revamp it slightly and attach an updated version. It includes a test for the protocol that fairly comprehensively tests the protocol. This is probably still something of a draft, though. There are a fair number TODOs and other crap in the code to clean up, so a better version will definitely follow. 

If anyone has time to take a look, dig into the code and let me know what you think.

> 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
