David Reiss commented on THRIFT-594:
------------------------------------
Yeah, I thought of that, but won't you have to pass a boolean around anyway to
determine if things should be interned at read-time or not?
> Add "intern" method to generated structs

> Key: THRIFT-594
> URL: https://issues.apache.org/jira/browse/THRIFT-594
> Project: Thrift
> Issue Type: New Feature
> Components: Compiler (Java), Library (Java)
> Affects Versions: 0.2
> Reporter: Bryan Duxbury
> Priority: Minor
> Fix For: 0.2

>
> Thrift structs can take up a lot of memory in Java. In my particular
> application, many of the structs I load have common subcomponents. When
> deserializing these structs today, each copy of the common subcomponents
> takes up a fresh chunk of memory.
> To reduce this memory usage, I propose that we add an "intern" method to
> Thrift structs. This method would maintain a static class-level cache of
> canonical versions of instances of objects. When calling "intern", if the
> object was not in the cache, it would add it and return the same struct. If
> it was in the cache, it would return the canonical version, allowing the
> non-canonical version to be dropped during garbage collection.
