Getting started

Migrate your PySpark application to e6data in Three steps: 1. Update imports 2. Configure the connection 3. Run

Getting Started

Step 1: Update Imports

Replace your PySpark imports with e6-spark-compat equivalents. The API is identical.

Before (PySpark)

from pyspark.sql import SparkSession
from pyspark.sql.functions import col, upper, count, sum, row_number
from pyspark.sql.window import Window

After (e6data)

For spatial (Sedona) operations:

Before (Sedona)

from sedona.register import SedonaRegistrator

After (e6data)

Step 2: Configure the Connection

Create a SparkSession pointing to your e6data cluster.

spark = SparkSession.builder 
    .appName("MyApp") 
    .config("spark.e6data.host", "<cluster-host>") 
    .config("spark.e6data.username", "<username>") 
    .config("spark.e6data.password", "<access-token>") 
    .config("spark.e6data.database", "<database>") 
    .config("spark.e6data.catalog", "<catalog>") 
    .config("spark.e6data.cluster", "<cluster-name>") 
    .config("spark.e6data.secure", True) 
    .getOrCreate()

Configuration Parameters

Parameter	Description	Required
spark.e6data.host	Cluster hostname or IP address	Yes
spark.e6data.username	e6data account email	Yes
spark.e6data.password	Personal Access Token from the e6data console	Yes
spark.e6data.database	Target database name	Yes
spark.e6data.catalog	Catalog name	Yes
spark.e6data.cluster	Cluster name	Yes
spark.e6data.secure	Use TLS for the connection (True or False). Default: True	No

You can find your cluster hostname and connection details in the e6data console under Clusters > Connection Info.

Do not hardcode your access token in source code. Use environment variables or a secrets manager instead.

Using Environment Variables

import os

spark = SparkSession.builder 
    .appName("MyApp") 
    .config("spark.e6data.host", os.getenv("E6DATA_HOST")) 
    .config("spark.e6data.username", os.getenv("E6DATA_USERNAME")) 
    .config("spark.e6data.password", os.getenv("E6DATA_TOKEN")) 
    .config("spark.e6data.database", os.getenv("E6DATA_DATABASE")) 
    .config("spark.e6data.catalog", os.getenv("E6DATA_CATALOG")) 
    .config("spark.e6data.cluster", os.getenv("E6DATA_CLUSTER")) 
    .config("spark.e6data.secure", True) 
    .getOrCreate()

Step 3: Run Your Code

Your existing PySpark logic works without modification.

# Read data
df = spark.read.parquet("s3://bucket/path/to/data.parquet")

# Transformations (lazy — no execution yet)
result = df.filter(col("age") > 21) 
    .select("name", "city", "salary") 
    .groupBy("city") 
    .agg(count("*").alias("total"), sum("salary").alias("total_salary")) 
    .orderBy(col("total").desc())

# Action triggers execution on e6data
result.show()

Catalog Operations

Discover databases, tables, and columns programmatically.

# List databases
spark.catalog.listDatabases()

# List tables in current database
spark.catalog.listTables()

# List columns of a table
spark.catalog.listColumns("my_table")

# Check if a table exists
spark.catalog.tableExists("my_table")

Closing the Session

spark.stop()
