Hi all,

In order to save data transfer (out) costs, we would want to stream the data compressed with gzip.

I have made some tries and it works, requesting directly to the API. Example (omitting values for the sake of simplicity):

#!/bin/bash

...

OBJECT="{'kind': 'bigquery#tableDataInsertAllRequest', 'skipInvalidRows': true, 'ignoreUnknownValues': true, 'rows': $ROWS}"

echo $OBJECT | gzip -cf > compressed.gz

curl -v -H "Authorization: Bearer $ACCESS_TOKEN" \
     -H "Content-Type: text/plain" \
     -H "Content-Encoding: gzip" \
     --data-binary @compressed.gz \
"https://www.googleapis.com/bigquery/v2/projects/$GOOGLE_CLOUD_PROJECT/datasets/$DATASET_ID/tables/$TABLE_ID/insertAll"

But I couldn't find where to set the header to change the content-encoding to gzip. I know it's an option to the responses and to store files ( https://github.com/googleapis/nodejs-bigquery/blob/fbe4f93f9167e904ee9d0beaf27f0d0b9da6d7bb/src/table.js#L728 ) but no for requesting.

Is it possible to add a new setting to allow compress or not? In that case, the responsibility of the compression is for the server, not for this module. I think it would be worth :)

Of course, I could help if needed.

Thanks!

Alfredo
