developer s facebook inc initial release may 2012 10 years ago 2012 05 stable release 7 9 2 1 21 december 2022 repository github com facebook rocksdb written in c operating system windows macos linux freebsd openbsd solaris aix platform x86 x86_64 ppc64 ppc64le aarch64 s390x type embedded database license apache 2 0 or gpl 2 website rocksdb org rocksdb is a high performance 2 3 4 5 6 embedded database for key value data it is a fork of google s leveldb optimized to exploit many cpu cores and make efficient use of fast storage such as solid state drives ssd for input output i o bound workloads it is based on a log structured merge tree lsm tree data structure it is written in c and provides official language bindings for c c and java alongside many third party language bindings rocksdb is open source software and was originally released under a bsd 3 clause license 7 8 9 however in july 2017 the project was migrated to a dual license of both apache 2 0 and gplv2 license 10 possibly in response to the apache software foundation s blacklist of the previous bsd patents license clause 11 12 rocksdb is used in production systems at various web scale enterprises 13 including facebook yahoo 14 and linkedin 15 features edit rocksdb like leveldb stores keys and values in arbitrary byte arrays and data is sorted byte wise by key or by providing a custom comparator rocksdb provides all of the features of leveldb plus transactions 16 backups 17 and snapshots 18 column families 19 bloom filters 20 time to live ttl support 21 universal compaction 22 merge operators 23 statistics collection 24 geospatial indexing 25 and others list of rocksdb features that are not in leveldb rocksdb is not an sql database although myrocks combines rocksdb with mysql like other nosql and dbm stores it has no relational data model and it does not support sql queries also it has no direct support for secondary indexes however a user may build their own internally using column families or externally applications use rocksdb as a library as it does not provide a server or command line interface history edit rocksdb was created at facebook by dhruba borthakur 26 27 in april 2012 as a fork of leveldb with the initial stated goal of improving performance for server workloads 28 29 integration edit as an embeddable database rocksdb can be used as a storage engine within a larger database management system dbms for example cockroachdb uses rocksdb as its storage engine 30 mostly for transactional workloads while rockset uses rocksdb mostly for analytical data processing this shows that rocksdb can be used as a storage engine for both online transaction processing and online analytical processing alternative backend edit the following projects have been started to replace or offer alternative storage engines for already established database systems with rocksdb arangodb edit arangodb has added rocksdb to its previous storage engine mmfiles 31 starting with arangodb 3 4 rocksdb will be the default storage engine in arangodb 32 cassandra edit cassandra on rocksdb can improve the performance of apache cassandra significantly 3 4 times faster in general 100 times faster in some use cases citation needed the instagram team at facebook developed and open sourced their code along with benchmarks of their performance results 33 mariadb edit mariadb can use the myrocks storage engine which is forked from rocksdb since mariadb 10 2 5 alpha status 34 and stable since mariadb 10 2 16 in 2018 35 mongodb edit the mongorocks project provides a storage module for mongodb where the storage engine is rocksdb 36 37 38 a related program is rocks strata a tool written in go which allows managing incremental backups of mongodb when rocksdb is used as the storage engine 39 mysql edit the myrocks project creates a new rocksdb based storage engine for mysql 40 41 in depth details about myrocks were presented at percona live 2016 42 ukv edit the ukv 43 project allows users to use rocksdb on par with leveldb as the underlying key value store it represents a shared abstraction for crud operations common to every storage engine it augments it with structured bindings for several high level languages like python java and go embedded edit the following database systems and applications have chosen to use rocksdb as their embedded storage engine ceph s bluestore edit the ceph s bluestore storage layer uses rocksdb for metadata management in osd devices 44 apache flink edit apache flink uses rocksdb to store checkpoints 45 fusiondb edit fusiondb 46 uses rocksdb as its storage engine for xml key value and json 47 logdevice logsdb edit logdevice s logsdb is built atop rocksdb 48 manhattan edit the manhattan distributed key value store has used rocksdb as its primary engine to store twitter data since 2018 49 rockset edit the rockset service that is used for operational data analytics uses rocksdb as its storage engine 50 ssdb edit the ssdb rocks 51 project uses rocksdb as the storage engine for the ssdb 52 nosql database tidb edit the tidb 53 project uses rocksdb as its storage engine 54 yugabytedb edit the yugabytedb 55 database uses a modified version of rocksdb as part of its docdb storage engine third party language bindings edit third party programming language bindings available for rocksdb include c 43 c 56 chicken scheme 57 d 58 elixir 59 erlang 60 61 go 43 62 haskell 63 java 43 64 node js 65 objective c and swift 66 ocaml 67 68 perl 69 php 70 prolog 71 python 43 72 ruby 73 rust 74 references edit https github com facebook
