Jonathan Ellis resolved CASSANDRA-2529.
---------------------------------------
Resolution: Not A Problem
Fix Version/s: (was: 0.8.0)
This is a case where the cli violates the second part of "as simple as
possible, but no simpler." The cli makes three assumptions for replication
strategy if it is not specified:
- you want NetworkTopologyStrategy (reasonable, but wait)
- you are using SimpleSnitch (not often the case in production -- and Snitch is
pluggable so it may not even be a Snitch class we ship with)
- you want one replica in the datacenter containing the node you are connecting
to (how is this intuitive?)
Now, I said defaulting to NTS is reasonable, but if we make that the default
and only require specifying strategy_options it confuses people when we then
explain that the options differ based on which strategy class you are using. So
it makes the most sense to keep everything explicit. ("in the face of
ambiguity, refuse the temptation to guess.")
tl;dr we screwed up, but rather than break peoples' CLI scripts we're taking
the opportunity offered by CQL to fix it.
