A writable stream that batches.

Example

``js
const createBulk = require('bulk-insert')

const onError = (err) => {
if (err) console.error(err.stack || err)
}

const writable = createBulk({
limit: 500, // maximum # of documents to insert at one time
interval: '0.5s', // minimum interval between flushes,
onError,
flush (data) {
// data will be an array
kinesis.putRecords({
Records: data.map((x) => ({
Data: JSON.stringify(x),
PartitionKey: 'some_key'
})),
StreamName: 'some_stream_name'
}, onError)
}
})

writable.write({
some: 'data'
})

writable.write({
some: 'more data'
})
`

Flushes immediately and unrefs all future timers, allowing the process to exit gracefully.
Even though you are still able to write to the stream after you've closed it, you should not.
