Subject Re: Crail project looking for mentors
Date Wed, 18 Oct 2017 12:59:29 GMT
What you did, sounds very like a DeJaVoux to me:

https://github.com/apache/activemq-artemis/tree/master/artemis-journal/src/main/java/org/apache/activemq/artemis/core/io

Some similarities:

- https://github.com/apache/activemq-artemis/blob/master/artemis-journal/src/main/java/org/apache/activemq/artemis/core/io/IOCallback.java


What I missed at crail..
- it's "only" client/server?
  * The interfaces seem easy enough to be standalone.. easy
refactoring if you agree
- The Crail Buffer makes dependencies hard.
  * I have made that mistake myself here:
    ** Look at ActiveMQBuffer at Artemis
   I sort of fixed that by depending on Netty..

Well... that is to say.. that I always looked for a some other place I
could store the Journal from Artemis. At least I looked for a place I
could place https://github.com/apache/activemq-artemis/tree/master/artemis-native...

This native bit is generic enough to be used on a IO project.


Having that said.. I have never been a mentor. I am a committer at
ActiveMQ Artemis and PMC member there. I will do some research about
what it takes.. I will also need to clear with my day job bosses.. but
if you help me having this integrated in Artemis (maybe refactor the
interfaces a bit)... it would help having my day job dedicated here
and not just my spare time.
