lmdbnav

A terminal UI to inspect LMDB database files.

This is a tool that we use internally to debug LMDB databases. We decided to open source it, since it can be useful to others.

Contributions are welcome.

Installation

From a local source checkout:

$ GOBIN=/path/to/target/bin go install ./cmd/lmdbnav

Or directly, without any local checkout:
