Supported pandas API # The following table shows the pandas APIs that implemented or non-implemented from pandas API on Spark. There isn't a direct slicing operation like in pandas (e. apply # DataFrame. To do this we will use the select () function. PySpark facilitates this by providing functional programming constructs that allow users to apply transformation logic directly to column data, thereby 0 Apache Spark is fundamentally not row-based as PySpark DataFrames are partitioned on one or more keys, and each partition is stored on a separate node. PySpark Overview # Date: Jan 02, 2026 Version: 4. explode(col) [source] # Returns a new row for each element in the given array or map. Need a substring? Just slice your string. slice() for more information about using it in real time with examples PySpark, widely used for big data processing, allows us to extract the first and last N rows from a DataFrame. Examples Example 1: Basic usage of the slice In python or R, there are ways to slice DataFrame using index. We Array function: Returns a new array column by slicing the input array column from a start index to a specific length. slice # pyspark. SparkContext. slice(start=None, stop=None, step=None) # Slice substrings from each element in the Series. These This function APIs usually have methods with Column signature only because it can support not only Column but also other types such as a native string. split(str: ColumnOrName, pattern: str, limit: int = - 1) → pyspark. substring(str: ColumnOrName, pos: int, len: int) → pyspark. column pyspark.
