The video tutorial introduces Pig Latin, a scripting language in the Hadoop ecosystem, as an alternative to writing MapReduce code. It highlights Pig Latin's SQL-like syntax, making it easier to define map and reduce steps without Java. The tutorial covers Pig Latin's extensibility with user-defined functions and its integration with Hive. A code example demonstrates its high-level syntax. The video also explains Pig's integration with AWS, allowing data queries on Amazon S3 and EMR. Despite being older technology, Pig Latin remains relevant for distributed data analysis.

What are user-defined functions in Pig and how do they enhance its functionality?

Describe the syntax of Pig Latin and how it compares to SQL.
