Partial deserialization
-----------------------
Key: THRIFT-446
URL: https://issues.apache.org/jira/browse/THRIFT-446
Project: Thrift
Issue Type: New Feature
Reporter: Bryan Duxbury
Priority: Minor
There are some use cases where you might have a fair amount of serialized data
coming to you, but you're only interested in specific fields from that data.
The way it works now, you are stuck paying the price to deserialize that extra
data no matter what.
In the simplest approach, it would be nice if you could specify some sort of
mask to use to suppress the deserialization of a given set of fields. A
slightly more complex approach would be to not just skip the deserialization,
but to actually hang on to the bytes that you didn't deserialize, so that when
it came time to re-serialize, you could just rewrite the original data.
Obviously this would imply some interesting interactions with the validation
system and probably nontrivial changes elsewhere (isset, protocol interface,
etc). However, it could yield a big performance benefit in specific
applications.
