schema-sample.txt: Comment explaining Quorum to counter beginner's mistake
--------------------------------------------------------------------------
Key: CASSANDRA-2705
URL: https://issues.apache.org/jira/browse/CASSANDRA-2705
Project: Cassandra
Issue Type: Improvement
Reporter: Timo Nentwig
Fix For: 0.7.7, 0.8.1
After stumbling upon this pitfall *twice* (yeah, it's okay to call me stupid,
but I'm your customer anyways :) I suggest a simple comment in the Keyspace1
example like this:
replication_factor defines the total number of nodes holding the data.
quorum with a RF < 3 provides no fault tolerance, because with a RF=2
data is written to 2 nodes in total (if one fails, only one remaining
can be checked while 2 are actually required to meet quorum).
