The number of stages created from the code provided depends on the specific code and its functionality.
The number of stages can vary based on the complexity of the code and the specific tasks being performed.
Stages may include data extraction, transformation, loading, and processing.
It is important to analyze the code and identify distinct stages to determine the total number.
Narrow transformation processes one record at a time, while wide transformation processes multiple records at once.
Narrow transformation processes one record at a time, making it easier to parallelize and optimize.
Wide transformation processes multiple records at once, which can lead to shuffling and performance issues.
Examples of narrow transformations include map and filter operations, while examples of wide transfor
Actions and transformations are key concepts in data engineering, involving the manipulation and processing of data.
Actions are operations that trigger the execution of a data transformation job in a distributed computing environment.
Transformations are functions that take an input dataset and produce an output dataset, often involving filtering, aggregating, or joining data.
Examples of actions include 'saveAsTextFile'...
Enforcing the schema ensures data consistency and validation, while manually defining the schema in code allows for more flexibility and customization.

Optimizations like partitioning, caching, and using efficient file formats can reduce overhead in reading large datasets in Spark.
Partitioning data based on key can reduce the amount of data shuffled during joins and aggregations
Caching frequently accessed datasets in memory can avoid recomputation
Using efficient file formats like Parquet or ORC can reduce disk I/O and improve read performance

List is mutable, Tuple is immutable in Python.
List can be modified after creation, Tuple cannot be modified.
List is defined using square brackets [], Tuple is defined using parentheses ().
Example: list_example = [1, 2, 3], tuple_example = (4, 5, 6)
Rank assigns a unique rank to each row, Dense Rank assigns a unique rank to each distinct row, and Row Number assigns a unique number to each row.
Rank assigns the same rank to rows with the same value, leaving gaps in the ranking if there are ties.
Dense Rank assigns a unique rank to each distinct row, leaving no gaps in the ranking.
Row Number assigns a unique number to each row, without any regard for the values in the...
List comprehension is a concise way to create lists in Python by applying an expression to each item in an iterable.
Syntax: [expression for item in iterable]
Can include conditions: [expression for item in iterable if condition]
Example: squares = [x**2 for x in range(10)]
Interactive clusters allow for real-time interaction and exploration, while job clusters are used for running batch jobs.
Interactive clusters are used for real-time data exploration and analysis.
Job clusters are used for running batch jobs and processing large amounts of data.
Interactive clusters are typically smaller in size and have shorter lifespans.
Job clusters are usually larger and more powerful to handle heavy w...
To add a column in a dataframe, use the 'withColumn' method. To rename a column, use the 'withColumnRenamed' method.
To add a column, use the 'withColumn' method with the new column name and the expression to compute the values for that column.
Example: df.withColumn('new_column', df['existing_column'] * 2)
To rename a column, use the 'withColumnRenamed' method with the current column name and the new column name.
Example:...
Coalesce is used to combine multiple small partitions into a larger one, while Repartition is used to increase or decrease the number of partitions in a DataFrame.
Coalesce reduces the number of partitions in a DataFrame by combining small partitions into larger ones.
Repartition increases or decreases the number of partitions in a DataFrame by shuffling the data across partitions.
Coalesce is more efficient than Repartit...
