A golang package which offers a simple abstraction on BadgerDB key/value store

Based on BadgerDB v0.9.0 API.


Creating or opening a store with Sett is identical to BadgerDB

opts := sett.DefaultOptions
opts.Dir = "data"
opts.ValueDir = "data/log"

s := sett.Open(opts)
defer s.Close()

Simple set, get and delete a key. Strings used in preference to byte slices.

s.Set("hello", "world")


Tables are virtual, simply a prefix on the key, but formalised through the Sett API. The aim being to make organisation, reasoning and usage, a little simpler.

Add a key/value to "client" table

s.Table("client").Set("hello", "world")

Get value of key from "client" table


Delete key and value from "client" table


Drop "client" table including all keys


Batch Set

Uses concurrent goroutines to split the insert payload, default is 500 keys per goroutine. To change this set the sett.BatchSize variable before opening connection.

sett.BatchSize = 50
s := sett.Open(opts)
defer s.Close()

Batch insert into "client" table

s.Batchup("hello", "world")
s.Batchup("hello-again", "world")
s.Batchup("goodbye", "world")


Get entire table, or subset of table

Use sett.Scan() to return contents of virtual table or a subset of that table based on a prefix filter.

Retrieving all key/values from the "client" table

scan, _ := s.Table("client").Scan()
for k, v := range scan {
	log.Println(k, v)

Using a prefix filter to get a subset of a key/values from "client" table. In the below example the key prefix filter is "hello"

scan, _ := s.Table("client").Scan("hello")
for k, v := range scan {
	log.Println(k, v)
