Re: about AOP development
Hi：
I found the ignite-aop module on github, and I asked what the module is
to do?
In addition, this module does not have a document.

Re: about AOP development
Posted by Dmitriy Setrakyan <ds...@apache.org>.
This module enables grid-enabling standard Java methods using @Gridify
annotation in conjunction with some AOP framework. However, AOP is no
longer a popular technology, and we thought that having documentation at
Javadoc level should suffice.
