nodeJs .pipe() process not ending

Got an not understandable problem with NodeJs pipe(), process is not ending and I had to ctrl+c for quit it, is it an asynchronous matter ?

const fs = require('fs')
const parse = require('csv-parse')
const customers = require('../db/collections').customers
const inputFile = 'mytable.csv'

const input = fs.createReadStream(inputFile)

const parser = parse({ columns: true }, (err, data) => {
  if (err) console.log(err)
   data.forEach(customer => {
    customers.create(customer)
  })
})

input.pipe(parser)
