I wonder if this could help Photon, the open source ElasticSearch/OpenSearch search engine for OSM data.

It's a mini-revolution in the OSM world, where most apps have a bad search experience where typos aren't handled.

A system built on LMDB will work better for this use case than RocksDB. And OSM Express already uses it. https://wiki.openstreetmap.org/wiki/OSM_Express
