Looks good, +1 with request for minor change:
I would pull out the setting of the merge operator from the option
factories. We should not allow users to override (or forget to set it), because
we make a hard assumption on the fact that exactly that merge operator is
configured.

> The latest release of RocksDB (5.5.5) fixes the issues from previous versions

> latest release.
