String Functions

In the world of streaming data processing, text manipulation is a vital aspect of many applications. To effectively handle various text processing tasks, Macrometa GDN Stream Workers offer an extensive set of string functions designed to perform a wide range of operations on text data in real time.

The string functions available for stream workers include concat, contains, hex, length, lower, trim, split, and many others. These functions enable you to perform operations such as concatenating strings, searching for substrings, converting text to hexadecimal representations, modifying text case, and splitting text based on specific delimiters.

This section explores the string functions offered by Macrometa GDN Stream Workers, showcasing their usage and highlighting their capabilities in text processing within streaming data pipelines.
