Spark Google Spreadsheets

Google Spreadsheets datasource for SparkSQL and DataFrames

Notice

The version 0.4.0 breaks compatibility with previous versions. You must use a ** spreadsheetId ** to identify which spreadsheet is to be accessed or altered. In older versions, spreadsheet name was used.

If you don't know spreadsheetId, please read the Introduction to the Google Sheets API v4.

CREATE TABLE cars
USING com.github.riskidentdms.spark.google.spreadsheets
OPTIONS (
    path "<spreadsheetId>/worksheet1",
    serviceAccountId "xxxxxx@developer.gserviceaccount.com",
    credentialPath "/path/to/credential.p12"
)

Scala API

TBD: Should be updated

import org.apache.spark.sql.SparkSession

val sqlContext = SparkSession.builder()
  .master("local[2]")
  .appName("SpreadsheetSuite")
  .getOrCreate().sqlContext

// Creates a DataFrame from a specified worksheet
val df = sqlContext.read.
    format("com.github.riskidentdms.spark.google.spreadsheets").
    option("serviceAccountId", "xxxxxx@developer.gserviceaccount.com").
    option("credentialPath", "/path/to/credential.p12").
    load("<spreadsheetId>/worksheet1")

// Saves a DataFrame to a new worksheet
df.write.
    format("com.github.riskidentdms.spark.google.spreadsheets").
    option("serviceAccountId", "xxxxxx@developer.gserviceaccount.com").
    option("credentialPath", "/path/to/credential.p12").
    save("<spreadsheetId>/newWorksheet")

Using Google default application credentials

TBD: Should be updated

Provide authentication credentials to your application code by setting the environment variable GOOGLE_APPLICATION_CREDENTIALS. The variable should be set to the path of the service account json file.

import org.apache.spark.sql.SparkSession

val sqlContext = SparkSession.builder()
  .master("local[2]")
  .appName("SpreadsheetSuite")
  .getOrCreate().sqlContext

// Creates a DataFrame from a specified worksheet
val df = sqlContext.read.
    format("com.github.riskidentdms.spark.google.spreadsheets").
    load("<spreadsheetId>/worksheet1")
