Connection-pool for RethinkDB
npm install --save rethinkdb-pool
var r = require('rethinkdb')
var createPool = require('rethinkdb-pool')
var pool = createPool(r, {
host:'localhost',
port:28015,
db:'marvel',
authKey:'hunter2'
})
var query = r.table('foo').limit(100)
// callback
pool.run(query, function (error, list) {
// no more acquire, no more toArray, yay!!
})
// promise
pool.run(query).then(function (list) {
// promise, yay
})
Connection can be acquired by calling the .acquire()
function, but the responsibility of managing resources can be quite challenging.
See: http://bluebirdjs.com/docs/api/resource-management.html
// Don't do this! Leaks resources!
pool.acquire().then(function (connection) {
r.table('aTable').limit(10).run(connection, function (error, cursor) {
if (error != null) {
return handleError(error)
}
cursor.toArray(function (error, data) {
if (error != null) {
return handleError(error)
}
console.log(data)
pool.release(connection)
})
})
})
