---------------------------------------
Summary: Thrift multi-threaded async Java Server using Java 7
AsynchronousChannelGroup
Key: THRIFT-1894
URL: https://issues.apache.org/jira/browse/THRIFT-1894
Project: Thrift
Issue Type: New Feature
Components: Java - Library
Affects Versions: 1.0
Environment: Windows/Linux/OS X
Reporter: Randy Abernethy
Fix For: 1.0
This is a Java async thread pool server which my shop would like to contribute
to 1.0.
This server creates a single thread pool to execute all client requests. Any
thread may be dispatched to service any request on any connection. Async
operations use direct ByteBuffers, allowing the underlying system to write
directly to the server buffer in some JVMs. No memory is typically copied by
the server, the Protocol reads directly from the I/O buffer. The HotSpot JVM
implements AsynchronousChannelGroups with I/O completion ports on Windows,
event port on Solaris, and epoll on Linux. The IOCP implementation makes a
noticeable difference in some scale out scenarios on Windows. Have found this
server to be good for large client counts and TThreadPoolServer to be a little
better with lower client counts (our experience only of course).
In the tar:
Server: TAsyncThreadPoolServer.java
Channel: TChannelManager.java
Transport: TFramedChannelTransport.java
Test: TestAsyncThreadPoolServer.java
Requires Java 7.
Happy to field questions and turn patches if needed.
