Catalyst is a cost-based optimizer for Apache Spark SQL. It generates efficient execution plans to execute SQL queries on data stored in DataFrames and RDDs, by estimating the cost of each possible execution plan using statistics from the dataset. The goal of Catalyst is to improve query performance, scalability, and resource utilization.
