this is very good news,

as a member of a recently set up witness called @swisswitness we had a full node on our roadmap somewhere but I will admit it was far in the future. This change in using RocksDB will bring this a lot closer to the present not only for us but for a lot of witnesses out there.

This will make running a full node at least an option for top 50 - 70 witnesses and not just top 30 ish. (very rough estimate)

We are currently only 114th in the ranking so anyone out there with some spare or unused witness votes:
