Introduction

This module closely follows leveldown and implements the same API. The difference is that leveldown is a binding for LevelDB while rocksdb is a binding for RocksDB, Facebook's fork of LevelDB.

It is strongly recommended that you use levelup in preference to rocksdb unless you have measurable performance reasons to do so. levelup is optimized for usability and safety. Although we are working to improve the safety of the rocksdb interface it is still easy to crash your Node process if you don't do things in just the right way.

If you are upgrading: please see UPGRADING.md.

Supported Platforms

We aim to support at least Active LTS and Current Node.js releases, Electron 5.0.0, as well as any future Node.js and Electron releases thanks to N-API. The minimum node version for rocksdb is 10.12.0.

The rocksdb npm package ships with prebuilt binaries for popular 64-bit platforms and is known to work on:

Linux (including ARM platforms such as Raspberry Pi and Kindle)
Mac OS
Solaris (SmartOS & Nodejitsu)
FreeBSD
Windows

When installing rocksdb, node-gyp-build will check if a compatible binary exists and fallback to a compile step if it doesn't. In that case you'll need a valid node-gyp installation.

If you don't want to use the prebuilt binary for the platform you are installing on, specify the --build-from-source flag when you install. If you are working on rocksdb itself and want to re-compile the C++ code it's enough to do npm install.

API

Please refer to leveldown for API documentation. The db.open(options, callback) method of rocksdb has a few additional options:

readOnly (boolean, default false): open database in read-only mode.
infoLogLevel (string, default null): verbosity of info log. One of 'debug', 'info', 'warn', 'error', 'fatal', 'header' or null (disable).

Contributing

Level/rocksdb is an OPEN Open Source Project. This means that:

Individuals making significant and valuable contributions are given commit-access to the project to contribute as they see fit. This project is more like an open wiki than a standard guarded open source project.

See the Contribution Guide for more details.

Git Submodules

This project uses Git Submodules. This means that you should clone it recursively if you're planning on working on it:

$ git clone --recurse-submodules https://github.com/Level/rocksdb.git

Alternatively, you can initialize submodules after cloning:

$ git submodule update --init --recursive

Publishing

Increment the version: npm version ..
Push to GitHub: git push --follow-tags
Wait for CI to complete
Download prebuilds into ./prebuilds: npm run download-prebuilds
Optionally verify loading a prebuild: npm run test-prebuild
Optionally verify which files npm will include: canadian-pub
Finally: npm publish

An in-range update of prebuild-install is breaking the build 🚨

Version 2.5.1 of prebuild-install was just published.

Branch	Build failing 🚨
Dependency	prebuild-install
Current Version	2.5.0
Type	dependency

This version is covered by your current version range and after updating it in your project the build failed.

prebuild-install is a direct dependency of this project, and it is very likely causing it to break. If other packages depend on yours, this update is probably also breaking those in turn.

Action required: Greenkeeper could not be activated 🚨

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

To enable Greenkeeper, you need to make sure that a commit status is reported on all branches. This is required by Greenkeeper because we are using your CI build statuses to figure out when to notify you about breaking changes.

Since we did not receive a CI status on the greenkeeper/initial branch, we assume that you still need to configure it.

If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with greenkeeper/.

We recommend using Travis CI, but Greenkeeper will work with every other CI service as well.

Once you have installed CI on this repository, you’ll need to re-trigger Greenkeeper’s initial Pull Request. To do this, please delete the greenkeeper/initial branch in this repository, and then remove and re-add this repository to the Greenkeeper integration’s white list on Github. You'll find this list on your repo or organiszation’s settings page, under Installed GitHub Apps.

Segmentation fault on Node.js 12.7.0

Doing anything with rocksdb on Node.js 12.7.0 results in following error:

Segmentation fault (core dumped)

On Linux this is what i see in kernel logs:

Tried to rebuild, but doesn't help, still the same error. Looks like modifications are needed to the library itself.

I'm on Ubuntu 19.10 if that makes any difference (yes, 19.10, rolling release).

npmignore windows build files

Thanks to irish-pub, I noticed some extra files that would be included in the npm package (deps/snappy/snappy.sln and a few others).

I think we have to make our .npmignore match .gitignore. Also, there's a couple of RocksDB directories we can exclude, e.g. https://github.com/Level/rocksdb/tree/master/deps/leveldb/leveldb-rocksdb/arcanist_util

Pass options to rocksdb?

Just testing this library and I noticed there are several Log.old.15036... files being generated.

this post says you can pass options to the c++ library, but don't know how you'd go about doing that with this library (no docs)

Is it possible to configure the number of old log files kept and/or disable logging entirely?

Use concurrent builds

As suggested by @lu4 in #143 (comment):

What I've also found that significant performance improvements are obtainable from using concurrent builds i.e. node-gyp -j 16 rebuild build option. So I suggest to look closer into your node-gyp-build child and check whether it is possible to use the above option for build perf improvement.

Compilation fails with "concurrent insert not supported" on FreeBSD 12

I try to run a project that uses RocksDB on FreeBSD 12.

I got this error when running npm install:

Huge node_modules rocksdb directory - 1.41GB (Windows)

I understand that this is a relatively big, complex piece of software, but was very surprised to see the disk usage quite that high. I am yet to investigate disk usage on Linux, where it would be deployed.

Are there any easy ways to clear out unnecessary files? Would it be worth having an optional cleanup stage as part of the build? My use case does not involve modifying the rocksdb source and recompiling, and I suppose speeding up recompilation is a reason why various files produced during compilation are left behind.

Remove outdated 'Getting Support' section from README.md

Disable info logs by default

Forked from #13.

Disable info logs
Add option (something like infoLogLevel) to enable them
Remove the destroy fix for Windows (#13 (comment))
Also disable info logs for repair() and destroy()
Also support infoLogLevel option on repair() and destroy() (would change the JS interface)

Destroy() creates directory on Windows

Repro:

test('destroy does not create a directory', function (t) {
  t.plan(3)

  const location = path.resolve('destroy-test')

  rimraf.sync(location)
  t.is(fs.existsSync(location), false, 'exists before')

  leveldown.destroy(location, function (err) {
    t.ifError(err, 'no error')
    t.is(fs.existsSync(location), false, 'exists after') // Fails
  })
})

Here's the relevant C++, comments mine:

Status DestroyDB(const std::string& dbname /*, .. */) {
  FileLock* lock;
  const std::string lockname = LockFileName(dbname); // "<location>/LOCK"
  Status result = env->LockFile(lockname, &lock); // Creates <location>/LOCK
  
  if (result.ok()) {
    // Delete files..
    // ..

    env->UnlockFile(lock);
    env->DeleteFile(lockname); // Succeeds, directory is empty
    env->DeleteDir(dbname);    // Yet this fails
  }

  return result;
}

The DeleteDir fails (silently) with:

IO error: Failed to remove dir: D:\xx\Level\rocksdb\destroy-test: Directory not empty

Invoke rocksdb destroy

I am trying to invoke rocksdb destroy, using the level-rocksdb package. I cannot see how to get to the leveldown API to do this. I tried db.db after creating a database but it says no such method.

In a related question, the database has a status of 'opening' after I open it, is there a way to wait for it to open? I know the first usage usually does this, but what if I want to close it right away (or in this case test destroy).

Perhaps because the database is not yet open the leveldown API is not exposed? If so it would be good to know how to await (Typescript style) for it to open in every case.

Hi,

Are there any plans to add support for using rocksDBs TTL feature? https://github.com/facebook/rocksdb/wiki/Time-to-Live

Move rocksdb to a git submodule

So, I'm working on moving all dependencies to Git Submodules (as discussed in Level/leveldown#522), but I'm not quite able to figure out what the exact version of RocksDB is.

So, I know it's somewhere in ^5.3.0, but no upstream tag (v5.3.3 to v5.3.6) exactly matches the code in the deps/leveldb/leveldb-rocksdb folder.

I guess I could try to find out the exact commit by digging into this a bit deeper (without 08fd9a3 I suppose), but would it be fine to upgrade to the latest 5.3 version (v5.3.6) instead if tests pass?

Rewrite to N-API

RocksDB version upgrade

Hi, I'm trying to upgrade RocksDB version used in this package:

I've downloaded latest release from RocksDB official github, replaced the contents of /deps/leveldb/leveldb-rocksdb with it.
Updated the leveldb.gyp to this content which can be also found in this diff and the whole fork can be found here.

(I've also temporarily removed some of the code to pinpoint the issue, please ignore those changes)

Now when I install the package locally the compilation phase goes smooth, package installs successfully but when I try to run the code through requiring the package I get runtime error

Any thoughts on how to deal with this issue?

Release 3.0.1 with [email protected]

"IO error: Failed to create dir: Invalid argument" when having non-latin characters in folder name (only on windows)

const rocksdb = require("rocksdb")

Mac works fine, only happened on Windows.

Open rocksdb in ReadOnly Mode

Is there an option that can be passed to level/rocksdb to open rocksdb in ReadOnly Mode? I see how to do it from native code, but not from the level(path, options). I would like to have one process in read/write mode, and another process in ReadOnly mode (even if that means it is only a snapshot of the database at the time of open, that is OK).

releases

I need to setup prebuilts for all the envs, how do you folks do that?
Also, can you add me to the appveyor team (or how does that work)?

travis, appveyor: remove 7, add 9

An in-range update of abstract-leveldown is breaking the build 🚨

Version 4.0.1 of abstract-leveldown was just published.

Branch	Build failing 🚨
Dependency	abstract-leveldown
Current Version	4.0.0
Type	dependency

This version is covered by your current version range and after updating it in your project the build failed.

abstract-leveldown is a direct dependency of this project, and it is very likely causing it to break. If other packages depend on yours, this update is probably also breaking those in turn.

createReadStream with Binary data

I have a database with key/value encoding: 'binary'. Both put/get work fine using a node Buffer as the key/value. Now I want to use createReadStream with a range (gte,le) and I am not getting results back. I tried a test with 'hex' encoding on the same values (in hex form derived from the Buffer objects) and it worked fine, just not with Buffers themselves. The BytewiseComparator is the default in the configuration.

My question is: When using the BytewiseComparator with binary keys (node Buffer objects) and createReadStream, does it still do a byte-by-byte comparison? My actual key is longer than the 'gte/le' range keys, but if it works byte-by-byte then the 'gte/le' keys definitely include the range of the data in the database. If it is doing a number comparison on the entire range key and data key then it would not be in the range, since there are fewer bytes in the range keys than the data.

Here is a pseudo example in hex representation of what the data looks like (spacing for readability):

gte key:
05000000 15 01000000 1a01 00 2201 00
data key:
05000000 15 01000000 1A08 5912F421E64A4000
lt: key:
05000000 15 02000000 1a01 00 2201 00

You can see that 01000000 1a01 < 01000000 1A08 < 02000000 1a01 based on a byte-by-byte comparison.

I can convert to using 'hex' encoding for the keys, but it would be great if I can get it to work with pure binary.

Any help appreciated.

Version 10 of node.js has been released

Version 10 of Node.js (code name Dubnium) has been released! 🎊

To see what happens to your code in Node.js 10, Greenkeeper has created a branch with the following changes:

Added the new Node.js version to your .travis.yml
The new Node.js version is in-range for the engines in 1 of your package.json files, so that was left alone

If you’re interested in upgrading this repo to Node.js 10, you can open a PR with these changes. Please note that this issue is just intended as a friendly reminder and the PR as a possible starting point for getting your code running on Node.js 10.

More information on this issue

Greenkeeper has checked the engines key in any package.json file, the .nvmrc file, and the .travis.yml file, if present.

engines was only updated if it defined a single version, not a range.
.nvmrc was updated to Node.js 10
.travis.yml was only changed if there was a root-level node_js that didn’t already include Node.js 10, such as node or lts/*. In this case, the new version was appended to the list. We didn’t touch job or matrix configurations because these tend to be quite specific and complex, and it’s difficult to infer what the intentions were.

For many simpler .travis.yml configurations, this PR should suffice as-is, but depending on what you’re doing it may require additional work or may not be applicable at all. We’re also aware that you may have good reasons to not update to Node.js 10, which is why this was sent as an issue and not a pull request. Feel free to delete it without comment, I’m a humble robot and won’t feel rejected 🤖

Upgrade tempy

IIRC it only dropped node 6 so we're good.

Action required: Greenkeeper could not be activated 🚨

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

Since we did not receive a CI status on the greenkeeper/initial branch, we assume that you still need to configure it.

We recommend using Travis CI, but Greenkeeper will work with every other CI service as well.
