Andres de la Peña commented on CASSANDRA-17188:
-----------------------------------------------
This new guardrail doesn't make any changes in the current structure and just
adds to the already existent guardrails section. The new properties don't
introduce measurement units and the only part that be mismatch CASSANDRA-15234
is whether we use "fail" or "abort". I'd be happy waiting for CASSANDRA-15234
if we think that the rebase it's easier. In the end we don't even have a
reviewer for this ticket yet, CASSANDRA-15234 is almost ready, and I'm already
waiting for that ticket before start working on other guardrails that will
require measurement units.
However, I don't think we should block any tickets adding new config properties
until we do some other config refactoring, especially because I fear we'll
always we waiting for some future config refactoring. I neither think we should
block work on new features as a means to push forward a certain redesign of
config that is yet to be agreed, especially if the features are ready and the
redesign looks far away.
I understand that what we are discussing here is a general freeze of the config
file, so no new properties can be added until we settle on a new design. If
that's the case we should probably have a discussion on the mail list to
globally impose that freeze, which can be done either before or after having
agreed to that design.
