node-pyspark

This module brings Apache Spark API to nodejs.

WARNING This package is still in its early stages of development, and not all pyspark APIs have been ported yet.

Usage

The API is very similar to the pyspark API with some notable differences:

• All Functions and methods take an object argument. The keys of which represent the function parameters in pyspark
• Most functions are synchronous (in perception), but some return a promise and can be awaited upon

// importing is similar to that in pyspark
const { SparkSession, DataFrame, types, } = require('./index').sql;

// create spark session
spark = SparkSession.builder.appName("SimpleApp").getOrCreate()

// create a dataframe
df = spark.createDataFrame({ data: [1, 2, 3], schema: types.IntegerType() })

// show returns a promise
await df.show()

// stop the sessions
spark.stop()
