Thrift::XS - Faster Thrift binary protocol encoding and decoding
use Thrift; use Thrift::Socket; use Thrift::FramedTransport; use Thrift::XS::BinaryProtocol; use MyThriftInterface; my $socket = Thrift::Socket->new( $host, $port ); my $transport = Thrift::FramedTransport->new($socket); my $protocol = Thrift::XS::BinaryProtocol->new($transport); my $client = MyThriftInterface->new($protocol); $transport->open; $client->api_call( @args );
Thrift::XS provides faster versions of Thrift::BinaryProtocol and Thrift::MemoryBuffer.
Thrift compact protocol support is also available, just replace Thrift::XS::BinaryProtocol with Thrift::XS::CompactProtocol.
To use, simply replace your Thrift initialization code with the appropriate Thrift::XS version.
For the best performance, you need to use a custom socket layer and both Thrift::XS::MemoryBuffer and one of Thrift::XS::BinaryProtocol or Thrift::XS::CompactProtocol. If using the standard BufferedTransport, FramedTransport, or HttpClient modules, performance will not be as good as it could be. In particular, HttpClient is incredibly bad, making a lot of very small (1-4 byte) sysread() and print() calls. A future version of this module will probably provide XS implementations of these other modules to help with this problem.
Here is a breakdown of the performance improvements of the various low-level methods. A given Thrift API call will make many write and read method calls, so your results will be some average of these numbers. For detailed numbers and to run your own benchmarks, see the bench/bench.pl script.
