Subject Re: Switching back to review-then-commit process

Personally, it's not clear to me why the decision on having RTC process 
for committers for most critical modules shows our immaturity in a sense 
of open source collaboration.

As Raul properly noted below, the committers were always using RTC 
informally for most of the modules trying to reach each other asking to 
check changes before they get merged. In my understanding it shows that 
Ignite committers takes care more on the quality of the contributions 
rather than on a number of patches that get merged in a day or in a 
week. The only thing we did for now is that we put this type of 
collaboration on a paper.

It's not feasible to create a super comprehensive test that will check 
all the cases, it's not realistic to document every line of the internal 
code. But it's always possible to check your contribution with a 
committer who is more experienced in a specific functionality, get his 
feedback and as a result grow your own expertise.

In my initial example I referred to Spark community that has a list of 
maintainers as well. I think that this rule didn't lead to the project 
stagnation but rather allowed to adopt Spark in tons of projects 
worldwide by delivering releases with high quality. At this moment 
Ignite community decided to go this way as well. We're free to change 
our decision later if something doesn't work.
