Thanks for providing the platform to post queries.

I have installed my own instances of valhalla and overpass using docker. The base OSM pbf file is same for both instances but underlying data model is different as they do different indexing using that pbf file. My question is, Can I use same underlying data structure of either valhalla or overpass to install nominatim instead of indexing different structure for nominatim?. It will save my hardware resources like RAM, disk space etc.

No. Nominatim has its own data structure.

Thank you Jochen Topf. Correct me If I am wrong, I know that nominatim uses PostgreSQL database where as valhalla uses tile graph data structure and overpass uses indexed data structure. Is there any tool/mechanism to convert valhalla/overpass data structure to nominatim data structure? OR Is it possible can valhalla/overpass do geocoding and reverse geocoding instead of having nominatim?
