Spark SQL is a Spark module for structured data processing while HQL (Hive Query Language) is used with Hadoop's Hive. The main differences are: n 1. Spark SQL supports more data sources compared to HQL.n 2. Spark SQL provides higher performance due to its in-memory data processing capabilities compared to HQL which relies on disk-based operations.n 3. Spark SQL can be used without having a physical database like Hive. However, it does support integration with Hive and other databases.
