Welcome to Hibari

Hibari is a production-ready, distributed, key-value, big-data store (NOSQL database). Hibari uses chain replication for strong consistency, high-availability, and durability. Hibari has excellent performance especially for read and large value operations.

Hibari Clients

As of Hibari v0.1 (since year 2010), only the native Erlang client is used in production. All other client APIs (Thrift, JSON-RPC, UBF, and S3) are still in proof of concept stage and only implement basic operations.

Hibari v0.5 will have a full-featured Thrift client.


Short-term roadmap (as of February 2013)

v0.1 series (unstable)

  • v0.1.10
    • Minor bug fixes
    • Update for Erlang/OTP R15
    • Support for building on Ubuntu, including ARMv7 architecture
    • Move S3 and JSON-RPC components out from Hibari distribution (remove from the repo manifests.) S3 and JSON-RPC will become separate projects and will use rebar to manage dependencies. (Hibari will continue using repo)

v0.5 series (unstable)

  • v0.5
    • A complete Thrift API (do, get_many, and testset flag for set and replace)
    • More hibari and hibari-admin commands (e.g. control and monitor scavenger)
    • Delete table operation, which is missing in v0.1 series
    • Server-side timestamp and rename (Server-side timestamp is required by Thrift API)
    • Server-side counter
    • The latest external libraries (ubf, ubf-thrift, riak-err)
    • Update for Erlang/OTP R16
    • Basho Bench driver

v0.6 series (stable)

  • v0.6
    • Source code package. Application developers can build Hibari without repo by using this package. (Hibari developers will continue using repo.)
    • Documentation rework
    • Sample codes
    • Cookbook for Opscode Chef for automated single-node and multi-node deployments
    • More QuickCheck and EUnit test cases

Unscheduled Features

  • MapReduce (mruby?)
  • SNMP support
  • LETS (Google LevelDB) or HanoiDB as an alternative key storage for optimizing RAM usage
  • Scavenger enhancements
  • Big writes/reads (append to a value and partial_read from a value)
