 A regular expression, or regex, is a sequence of characters that defines a search pattern for text. Regex is commonly used for a variety of tasks including pattern matching, data validation, data transformation, and querying. It offers a flexible and an efficient way to search, manipulate, and handle complex data operations.

 This implementation of regular expression is based on the [RE2 regular expression library](https://github.com/google/re2/).

 ### What is the performance impact of using regex?
 
-Regex queries may have a performance impact depending on the complexity of the regex pattern, the size of the text data, and the number of rows involved. You can use the execution plan and statistics to monitor and optimize the performance of your regex queries.
