cluster-levelup

An opinionated isomorphic wrapper around levelup for cluster compatibility.

Doesn't includes backend, you can use leveldown, memdown or your own.

Master is always considered the database "opener", workers communicate with the database via RPC calls.

More goodness

You can find more useful stuff for levelup on awesome.

Example

Just use as if you were using levelup on the workers.

const levelup = require('cluster-levelup')
const cluster = require('cluster')

if (cluster.isMaster) {
  levelup(require('memdown')(), {}, (err, db) => {
    if (err) {
      throw err
    } else {
      db.put('test', 'value', (err) => {
        if (err) {
          throw err
        } else {
          console.log('Forking')
          cluster.fork()
        }
      })
    }
  })
} else {
  levelup.get('test', (err, data) => {
    if (err) {
      throw err
    } else {
      console.log('test', '=', data)
    }
  })
}
