The point Christophe made about lack of prefix compression in keys is especially important. I think this is a common enough layer concern that it should probably become an optional storage engine feature someday (as discussed here: [Discussion thread for new storage engine ideas](https://forums.foundationdb.org/t/discussion-thread-for-new-storage-engine-ideas/101/6)).
