Jake Farrell updated THRIFT-3306:
---------------------------------
Component/s: Java - Library
> Java: TBinaryProtocol: Use 1 temp buffer instead of allocating 8
> ----------------------------------------------------------------
>
> Key: THRIFT-3306
> URL: https://issues.apache.org/jira/browse/THRIFT-3306
> Project: Thrift
> Issue Type: Improvement
> Components: Java - Library
> Reporter: Evan Jones
> Priority: Minor
>
> TBinaryProtocol has a member buffer for reading and for serializing each of
> the integer types. It can get by with only a single one: 8 bytes long for the
> maximum length integer. This causes a significant reduction in allocations
> and GC in cases that create the TBinaryProtocol to serialize a single
> message, instead of reusing it.
> This passes "ant test". I ran the existing SerializationBenchmark and there
> is no statistically significant difference (the average of 5 runs is smaller
> on my machine, but I don't think we should read much into that).
> I have a JMH benchmark for this, and it shows that when the TBinaryProtocol
> is allocated each time, this change is better, but is more or less the same
> when you reuse the TBinaryProtocol in a loop.
