Bryan Duxbury updated THRIFT-110:
---------------------------------
Attachment: thrift-110-v9.patch
This version of the patch improves the performance of the compact protocol in
java to very close to the performance of the binary protocol - it only takes
about 16% longer.
I think that we're getting really close to being able to commit this protocol.
Can interested parties review at least the protocol spec? If we can finalize
the spec, we can fork this issue off into implementations for each library.
> 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
