Mastering HPCC Systems: ECL Cookbook

Front Cover
Richard Taylor, Jan 18, 2024 - Computers - 204 pages

HPCC Systems is an Open Source Big Data supercomputing platform that is an alternative to the Hadoop and Spark worlds. The Mastering HPCC Systems series introduces the HPCC Systems platform to anyone interested in evaluating it for use on their own big data projects. It also expands the ECL programming knowledge of anyone already working with the platform.

This ECL Cookbook volume provides a large number of discrete "tips and tricks" articles that describe various useful ECL programming techniques not already covered in the other volumes of this series. The articles are organized into sections that cover working with data files, index files, strings, dates, sets, and math functions. The code described provides a very useful set of library functions that can be used as-is, or as the basis for your extrapolation to solve related problems using the same techniques.
