NDN persistent content store

While LRU in-memory cache is usually good enough for simple NDN application, persistent disk-based content store is required if an application has a huge dataset.

It uses Bolt, and implements ndn.Cache interface.

Overview

Package persist implements persistent content store.

Index

• func Cacher(file string) mux.Middleware
• func New(file string) (ndn.Cache, error)

Functions

func Cacher

func Cacher(file string) mux.Middleware

Cacher creates a new caching middleware instance that uses the given file as the persistent content store.

func New

func New(file string) (ndn.Cache, error)

New creates a persistent content store.

By design, reading from this store is significantly faster than writing new entry. This store will not delete any old entry. When the file is opened, invoking New again will block.
