The only point here that would make a difference in practice is
leveldb using a worse hash function. For us it's not worth making
partitioning worse to make compaction better.
then use two hash functions. one for spliting rows to nodes and second
for index inside leveldb.
too much compactions is major problem of leveldb implementation in
cassandra. Cassandra implements initial leveldb design ignoring
improvements in about last 2 years in leveldb. You can try it yourself
by benchmarking original and current leveldb.
