pg-batch-query

Batches queries by using the Extended query protocol. Essentially we do the following

• send a single PARSE command to create a named statement.
• send a pair of BIND and EXECUTE commands
• Finally send a SYNC to close the current transaction.

As per benchmark tests, number of queries per seconds gets tripled using batched queries.

installation

$ npm install pg --save
$ npm install pg-batch-query --save

use

const pg = require('pg')
var pool = new pg.Pool()
const BatchQuery = require('pg-batch-query')

const batch = new BatchQuery({
  name: 'optional',
  text: 'SELECT from foo where bar = $1',
  values: [
    ['first'],
    ['second']
  ]
})

pool.connect((err, client, done) => {
  if (err) throw err
  const result = client.query(batch).execute()
  for (const res of result) {
    for (const row of res) {
      console.log(row)
    }
  }
})
