Hypercore + Corestore Interconnection

Overview

Corestore: Factory/namespacer for Hypercores. Efficient multi-core mgmt.

Why? Hypercore ctor expensive; corestore pools storage/replication.

Flow

graph LR
    App[new Corestore('./ns')] --> Core1[store.get(null)] %% new
    App --> Core2[store.get(key)] %% load
    App --> Named[store.get('db')] %% namespace
    Core1 -.-> Replicate[store.replicate(conn)]
    Core2 -.-> Replicate

API Synergy

const Corestore = require('corestore')
const store = new Corestore('./data')

const log = store.get(null) %% anon writable
const idx = store.get(null, {valueEncoding: 'json'}) %% readonly?

await store.replicate(conn) %% All cores over 1 stream!

Namespace: get('logs/chat') → keyed core.

Benefits: Shared bitfields/proofs, atomic sessions.

Hyperdrive Ex: drive.db = Hyperbee(corestore.get('db'))

Scale: 1000s cores, e.g. user shards.
