Simple question. Why "porting" zmq on java and call it JeroMQ is good idea?
回答1:
JeroMQ is an official project of the ZeroMQ community; it's a full port of the C++ libzmq library, supporting version 3.2.
Advantages:
- Pure Java, so no need to link in C/C++ via JNI. This is extremely helpful on devices where native libraries are difficult or impossible.
- 100% compatible with the JZMQ API (the two projects agreed on a single API so you can import one or the other transparently).
- 100% compatible with the ZeroMQ wire protocol, so you can run some nodes using JeroMQ and some using the native library, and it works as expected.
- Good performance, relatively close to the native library.
Disadvantages:
- No PGM multicast - there is no Java version of that library yet.
- Does not yet support ZeroMQ v4 functionality, including security.
回答2:
JeroMQ is a pure Java implementation of ZeroMq. If your target language is Java, it's easier to get started with JeroMq since it uses a single jar file. ZeroMq (zmq), on the other hand, is written in C. You must build zmq, libzmq, and the Java language bindings, jzmq, to use it in a Java app. The JeroMq API is identical to jzmq, so starting with JeroMq and switching to jzmq later has no impact on your application with the exception of performance; zmq performs better than JeroMq.
Hope that helps,
