About unitdb

Key characteristics

  • 100% Go
  • Can store larger-than-memory data sets
  • Optimized for fast lookups and writes
  • Supports writing billions of messages (or metrics) per hour with very low memory usages
  • Supports opening database with immutable flag
  • Supports database encryption
  • Supports time-to-live on message entries
  • Supports writing to wildcard topics
  • Data is safely written to disk with accuracy and high performant block sync technique

Quick Start

To build unitdb from source code use go get command.

go get -u github.com/unit-io/unitdb


Detailed API documentation is available using the go.dev service.

Make use of the client by importing it in your Go client source code. For example,

import "github.com/unit-io/unitdb"

The in-memory key-value data store persist entries into a WAL for immediate durability. The Write Ahead Log (WAL) retains memdb data when the db restarts. The WAL ensures data is durable in case of an unexpected failure. Make use of the client by importing in your Go client source code. For example,

import "github.com/unit-io/unitdb/memdb"

The unitdb supports Get, Put, Delete operations. It also supports encryption, batch operations, and writing to wildcard topics. See usage guide.

Samples are available in the cmd directory for reference.
