One sort of related question: given that order of insertions has huge
effects on some stores, like BDB (where inserting in key order is 10x
faster than arbitrary order), would insertion order possibly have
significant effect on Cassandra as well if using such stores? I bring
this up because what we found out when creating local bdbs was that
doing disk-sort before inserting big data sets allowed radically
faster creation of these (read-only) databases.
