馃敩 Rockspector

A lightweight inspector for RocksDB databases.

Rockspector provides:

Interactive web UI

Browse SST files

Browse WAL files

View LSM tree

Inspect MANIFEST state

Scan keys

Explore RocksDB metadata

Internally it wraps the standard rocksdb_ldb and rocksdb_sst_dump tools.

Requirements

Install rocksdb:

brew install rocksdb

Installation

npm i -g rockspector

Usage

Open any RocksDB database:

rockspector /path/to/db

Or pass a custom decoder:

rockspector /path/to/db --decoder ./example-decoder.js

Rockspector will start a local web server and print something like:

Rockspector: http://localhost:51342

Open the URL in your browser.

The server automatically chooses a free port, so multiple databases can be inspected simultaneously.

const db = new RocksDB("/path/to/db");

console.log(await db.summary());<br>console.log(await db.columnFamilies());<br>console.log(await db.keys());<br>console.log(await db.sstInfo("000123.sst"));
