--------------------------------------
Component/s: C++ - Library
> Compact Protocol improvement: combine sequence of multiple STOP fields
> together
> -------------------------------------------------------------------------------
>
> Key: THRIFT-704
> URL: https://issues.apache.org/jira/browse/THRIFT-704
> Project: Thrift
> Issue Type: Improvement
> Components: C++ - Library
> Affects Versions: 0.2
> Reporter: Bryan Duxbury
> Assignee: Bryan Duxbury
>
> One thing I've noticed looking at some of our compact-protocol-serialized
> structs is that we often have a sequence of STOP markers at the end of the
> stream. This occurs when you have a relatively deep object tree - once you
> are done serializing the last "leaf" object, you will write out a number of
> STOP fields equal to the height of the tree. Strictly speaking, there will be
> benefit found in the last leaf node of every subtree, not just the last leaf
> node of the entire tree.
> It should be possible to compress these STOPs together by packing a count
> into a single STOP. Then, when reading, the protocol can sort of pre-buffer
> the correct number of STOPs. These changes would leave the protocol
> implementation backwards compatible from the reading perspective, but not
> from the writing perspective. As such, I would probably add a flag to enable
> and disable this behavior when writing.
