- Support for Streaming RPCs.
- Support for using DirectExecutor.
- Support for specifying a client payload size.
- Support to export the histogram / latency distribution to file,
so that it can be visualized with a third party tool.
- Support setting the server / client flow control window for the connection and stream.
- Improved output format.
- Update README to include some JVM tuning and profiling information.
- Latencies are no longer reported in nanos, but in micros instead.
- Change warmup period to run the same code as in the actual benchmark.
- Can no longer specify the total number of concurrent RPCs, but instead
the number of concurrent RPCs per channel.
- Import the .proto file used by the C++ QPS package.
- Code Cleanup.
Commit 76f0a09 after the previous release
(ws.antonov.gradle.plugins:gradle-plugin-protobuf:0.9.1) defers the
generation of generateProto tasks to post-evaluation of the project,
which make them no longer available in the evaluation phase. We need to
move the manipulation of these tasks to post-evaluation too.
1. Adds <property name="separateLineBetweenGroups" value="true"/> to CustomImportOrder to enfore blank line between imports groups.
2. Uses checkstyle 6.5, which fixed a bug of "CustomImportOrder checks import sorting according to ASCII order instead of case-insensitive alphabetical order".
The checkstyle.xml is a slightly modified version of the upstream Google
checkstyle configuration. All changes have comment describing them.
Lots of warnings were corrected. Examples is the only project that has
warnings still, as the necessary changes require some thought.
Protoc should be in PATH and the project properties protobuf.include and
protobuf.libs should be set. For example:
gradlew build -Pprotobuf.include=C:\path\to\protobuf-3.0.0-alpha-2\src ^
-Pprotobuf.libs=C:\path\to\protobuf-3.0.0-alpha-2\vsprojects\Release
When running more than once, it is probably more convenient to create
%HOMEDRIVE%%HOMEPATH%\.gradle\gradle.properties with contents like:
protobuf.include=C:\\path\\to\\protobuf-3.0.0-alpha-2\\src
protobuf.libs=C:\\path\\to\\protobuf-3.0.0-alpha-2\\vsprojects\\Release
The QpsClient no longer executes a fixed number of RPCs but runs for a period of time now (see #83).
After some discussion with @ejona86, we also agreed to remove the "server_threads" parameter
and to no longer use a `DirectExecutor` and thus run the QPS Server without any tweaks and
modifications. We believe/hope that this change will make the comparison between the C++ and
Java versions less "Apples and Oranges".
The "client_threads" parameter was renamed to "concurrent_calls" to better reflect what it
acutally does.
Furthermore, I updated the gradle build script to create separate executables for the
client and the server.
I also added a README.
