Treeless

Distributed NoSQL key-value DB written in Go.

Features

• High performance (~1MOp/s per node)
• High availability (AP system with eventual consistency)
  • Last Writer Wins policy
  • Read-repair
  • Asynchronous repair
• Automatic rebalance
• Simple API (Get, Set, Del and CAS operations)
• Storage
  • Index always stored in RAM
  • Key-value pairs stored in RAM, SSD or HDD (memory mapped files are used)

API Example

c, err := client.Connect(addr)
c.Set([]byte("hola"), []byte("mundo"))
value, _, _ := c.Get([]byte("hola"))
c.Close()

CLI Example

Creating a new database:

./treeless -create -port 10000 -dbpath DB0 -localip 127.0.0.1  -redundancy 2

Adding a new node to an existing database:

./treeless -assoc 127.0.0.1:10000 -port 10001 -dbpath DB1 -localip 127.0.0.1

Status

All tests are passed, but you may still find serious bugs. Use with care.
