David Reiss commented on THRIFT-110:
------------------------------------
That would require the ability to instantiate an object given the "short code"
when reading. There are two difficulties there. The first is guaranteeing
uniqueness. The second is looking up the code and choosing the class
dynamically. Both are surmountable, but I believe that they add more
complexity than value to Thrift, compared to the union-like-struct-based
approach.
> A more compact format

> Key: THRIFT-110
> URL: https://issues.apache.org/jira/browse/THRIFT-110
> Project: Thrift
> Issue Type: Improvement
> Reporter: Noble Paul
>
> 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
