This is the first in a series of four blogs focusing on different usage perspectives for HPCC Systems. In this blog, George Foreman provides a high level overview of how to use our play cluster with either the ECL IDE or ECL Extension for VS Code and shows you how to get setup on ECL Watch to prepare you for using our platform.
ECL Provides a powerful capability to combine the benefits of declarative programming (ECL) with those of procedural languages such as C++, Java, or Python. This is known as Embedding. This guide provides a comprehensive review of various methods and patterns for Python Embedding within ECL programs. It reviews elementary embedding techniques, and provides a guide to several more advanced embedding patterns.
We know our big data analytics solution makes it easy for users to get up and running fast. While we demonstrate this through our training courses, documentation, tutorials and blog, what can be better than hearing it from a user who wants to share their experience and tips to the rest of our open source community. In this blog, Akhilesh Badhri talks about his HPCC Systems and ECL adoption journey.
Our 2021 Community Day Summit included three workshops focusing on some of our machine learning bundles. All sessions were recorded. Come and complete the full course at your leisure. Join our trainers, Bob Foreman and Hugo Watanuki as they demonstrate how to use DBSCAN, K-Means, Logistic and Linear Regression, Generalized Neural Networks and Learning Trees.
Throughout 2020, we have been adding new features and enhancements to our ECL Extension for VS Code and the latest version is available from the Visual Studio Marketplace. In this blog, Gordon Smith provides details of the feature highlights and enhancements recently added. These include simplified launch configurations, new workunit history view, a results viewer, access to additional resources such as bundles and client tools, the ability to insert record definitions, localisations to make this tool more accessible to those who speak a language other than English and a note about previously added Syntax Colouring that was adopted by GitHub earlier this year.
This ECL Tip spotlights the Enterprise Control Language (ECL) AGGREGATE built-in function. ECL AGGREGATE has been seen by many in the community as ‘complex,’ and as such, has been underused. However, in using AGGREGATE you can be sure you’re playing to the strengths of HPCC Systems.
This ECL Tip spotlights the Enterprise Control Language (ECL) DISTRIBUTE function. The ECL DISTRIBUTE function redistributes data across all nodes in a cluster. Using the DISTRIBUTE function can help prevent “cluster skew”, by distributing data evenly across all nodes. This function can be used on Thor or the ROXIE cluster.
This ECL Tip spotlights the Enterprise Control Language (ECL) TABLE function. The TABLE function is a versatile tool for ETL (extract, transform, load) operations, and was one of the first ECL statements available, well before the family of TRANSFORM functions.
This ECL Tip spotlights the top ten most common Enterprise Control Language (ECL) compiler/runtime errors, and how to correct them. Developers often encounter these specific errors while learning ECL. Most of these errors are easy to fix, but it is important to understand what the error message is saying and what needs to be corrected.
This ECL Tip spotlights the Enterprise Control Language (ECL) SET and the functions that incorporate SET. ECL SET is a useful tool in query design and processing. One of the most common applications for ECL SET is to simplify code by eliminating multiple “OR” conditions in a filter.
