How to use mongoDB with tendermint?

Question

Currently the default db of tendermint is LevelDB but i want to use mongoDB and did not find any helpful documentation over it. So, can anybody help or is it even possible? It's possible, i saw, but how?

Hi, you can follow the steps given below to solve your issue:

• create a new file libs/db/mongo_db.go
• write code [ you may refer this https://github.com/tendermint/tmlibs/blob/d9525c0fb671204450b160807480e1263053fb20/db/mem_db.go]
• add the new backend MongoDBBackendStr to db.go
• change the local tendermint configuration to use the new backend db_backend = "mongodb"
