EZ DB

This package provides simple interfaces for working with basic key-value document storage in your Go application.

System requirements

• Go v1.21

Basic usage

The primary interface in EZ DB is Collection[T] which reflects a single key-value store. This is analogous to tables in RDBMS, collections in NoSQL databases etc.

Collections use a generic type T to specify the document type. You can use this to enforce a document schema. This example creates a collection which only accepts Student documents:

package main

import "github.com/annybs/ezdb"

type Student struct {
	Name string
	Age int
}

var db = ezdb.Memory[Student](nil)

func main() {
	db.Open()
	db.Put("annie", Student{Name: "Annie", Age: "32"})
	db.Close()
}

Marshaling data

Some database backends require marshaling and unmarshaling data. The DocumentMarshaler[T1, T2] interface allows you to use whatever marshaler suits your needs or the requirements of your chosen database.

The following marshalers are included in EZ DB:

• JSON[T] marshals your data T to []byte using encoding/json

Supported databases

The following databases are included in EZ DB:

• LevelDB[T] is fast key-value storage on disk
• Memory[T] is essentially a wrapper for map[string]T. It can be provided another Collection to use as a persistence backend

Limitations

EZ DB is intended for simple document storage and can work with any addressable data represented as T in your Go app.

This makes it unsuited for working with unaddressable types, such as byte arrays, particularly when a document marshaler is involved.

If you want more control beyond what EZ DB offers, it's best to just use the appropriate database software and connector for your needs.
