-
Start Coding:
- Now you're ready to start writing code! Here's a simple example to get you started. This Python code reads a text file and counts the number of words:
from pyspark.sql import SparkSession # Create a SparkSession spark = SparkSession.builder.appName("WordCount").getOrCreate() # Read a text file text_file = spark.read.text("dbfs:/FileStore/tables/my_text_file.txt") # Split the lines into words words = text_file.rdd.flatMap(lambda line: line[0].split(" ")) # Count the words word_counts = words.map(lambda word: (word, 1)).reduceByKey(lambda a, b: a + b) # Print the results for word, count in word_counts.collect(): print(f"{word}: {count}") # Stop the SparkSession spark.stop() -
Run Your Code:
- To run a cell, just click on it and press
Shift + Enter. The results will be displayed below the cell.

Optimizing Your Databricks Community Edition Experience
To really make the most of Databricks Community Edition, you'll want to optimize your workflow and manage resources effectively. Here are some tips and tricks to help you do just that.
- Use Efficient Data Formats: Whenever possible, use efficient data formats like Parquet or Avro. These formats are optimized for Spark and can significantly reduce the amount of data that needs to be processed.
- Optimize Spark Configurations: Spark has a ton of configuration options that you can tweak to improve performance. Pay attention to settings like
spark.executor.memory,spark.executor.cores, andspark.default.parallelism. Experiment with different values to find the optimal configuration for your workload. - Cache Data: If you're performing multiple operations on the same dataset, consider caching it in memory. This can significantly speed up your computations.
- Use Broadcast Variables: Broadcast variables are a way to efficiently distribute read-only data to all nodes in your Spark cluster. This can be useful for things like lookup tables or configuration data.
- Avoid Shuffles: Shuffles are one of the most expensive operations in Spark. Try to minimize the number of shuffles in your code by using techniques like partitioning and bucketing.
- Monitor Your Jobs: Keep an eye on the Spark UI to monitor the performance of your jobs. This can help you identify bottlenecks and optimize your code.
By following these tips, you can significantly improve the performance of your Databricks Community Edition environment and get more done with limited resources.
