ECL Language Reference. ECL is the Enterprise Control Language designed specifically for huge data projects using the HPCC Systems platform. Its extreme scalability comes from a design that allows you to leverage every query you create for re-use in subsequent queries asneeded.
ECL IDE AND CLIENT TOOLS The ECL IDE and HPCC Systems Client Tools. This manual contains documentation for the set of Client Tools for use with the HPCC Systems platform. These tools include: ECL IDE, ECL Debugger, ECLPlus, ECL Command Line, ECL Compiler, ESDL Command Line, and DFUPlus. Release (v 8.0.14-1) View the PDF. View HTML. Beta (v {current_version}) View the PDF. ECL TIPS - THE TOP TEN ECL COMPILER/RUNTIME ERRORS AND HOW To fix this error, restart your ECL IDE and verify cluster connection. In the screenshot below, the Target says “Local.”. If you encounter this, try to change the Target to “THOR,” “Roxie, or “HTHOR.”. If you are unable to change the Target, there is a loss of connection with the cluster, and you need to reboot.AVAILABLE PROJECTS

DEPLOYING HPCC SYSTEMS ON MICROSOFT AZURE Massive computation workflows utilize High Performance Computing Cluster (HPCC) Systems environments that require significant resources, but these resources are only needed during processing. A commercial cloud service is a great resource to facilitate a short term need for computing capacity, without a long term commitment. It allows the user to access computing services, such as servers VISUALIZING ECL AND SHARING YOUR RESULTS Wherever you look these days, analysts are providing visual representations of the data they mine to help businesses make decisions. Since data is our business, this is something we have been doing for some time now, using the visualization capabilities built in to HPCC Systems®. The new HPCC Systems Visualizer Bundle allows you to visualize results generated by your ECL code rather thanROW | HPCC SYSTEMS
A RECORD structure that defines how to construct the row of data, similar to the type used by TABLE. transform. A TRANSFORM function that defines how to construct the row of data. Return: ROW returns a single record. The ROW function creates a single data record and is valid for use in any expression where a single record is valid. IMPORT | HPCC SYSTEMS IMPORT. A comma-delimited list of folder or file names in the repository. The dollar sign ($) makes all definitions in the current folder available. The caret symbol (^) can be used as shorthand for the container of the current folder. Using a caret within the module specifier (such as, myModule.^) selects the container of that folder.SET | HPCC SYSTEMS
The SET function returns a SET for use in any set operation (such as the IN operator), similar to a sub-select in SQL when used with the IN operator. It does not remove duplicate elements and does not order the set. One common problem is the use of the SET function in a filter condition, like this: 1. 1.

The INTERFACE structure defines a structured block of related members that may be passed as a single parameter to complex queries, instead of passing each attribute individually. It is similar to a MODULE structure with the VIRTUAL option, except errors are given for private (not SHARED or EXPORTed) member definitions. An INTERFACE is an abstract structure--a concrete instance must be definedROW | HPCC SYSTEMS
A RECORD structure that defines how to construct the row of data, similar to the type used by TABLE. transform. A TRANSFORM function that defines how to construct the row of data. Return: ROW returns a single record. The ROW function creates a single data record and is valid for use in any expression where a single record is valid.RESET YOUR PASSWORD
Username or email address. Password reset instructions will be sent to your registered email address. ROLLUP | HPCC SYSTEMS The ROLLUP function is similar to the DEDUP function with the addition of a call to the transform function to process each duplicate record pair. This allows you to retrieve valuable information from the "duplicate" record before it's thrown away. Depending on how you code the transform function, ROLLUP can keep the LEFT or RIGHT record, or any mixture of data from both.

VISUALIZING ECL AND SHARING YOUR RESULTS Wherever you look these days, analysts are providing visual representations of the data they mine to help businesses make decisions. Since data is our business, this is something we have been doing for some time now, using the visualization capabilities built in to HPCC Systems®. The new HPCC Systems Visualizer Bundle allows you to visualize results generated by your ECL code rather thanINTERFACE STRUCTURE
The INTERFACE structure defines a structured block of related members that may be passed as a single parameter to complex queries, instead of passing each attribute individually. It is similar to a MODULE structure with the VIRTUAL option, except errors are given for private (not SHARED or EXPORTed) member definitions. An INTERFACE is an abstract structure--a concrete instance must be definedROW | HPCC SYSTEMS
A RECORD structure that defines how to construct the row of data, similar to the type used by TABLE. transform. A TRANSFORM function that defines how to construct the row of data. Return: ROW returns a single record. The ROW function creates a single data record and is valid for use in any expression where a single record is valid.RESET YOUR PASSWORD
Username or email address. Password reset instructions will be sent to your registered email address. ROLLUP | HPCC SYSTEMS The ROLLUP function is similar to the DEDUP function with the addition of a call to the transform function to process each duplicate record pair. This allows you to retrieve valuable information from the "duplicate" record before it's thrown away. Depending on how you code the transform function, ROLLUP can keep the LEFT or RIGHT record, or any mixture of data from both.

Our tools make managing your data easy. Tombolo catalogs all the data assets in your data lake, includingrelationships.
ECL Cloud IDE makes learning ECL easy by providing rich integration between data and code without needing to install client software. Our powerful data engines execute automatically in a highly performing, parallel work stream. Thor, our data refinery engine, let’s you take control of data transformation. Thor can easily profile, clean, enhance, transform, and analyze mixed-schema data. ROXIE is an index-based search engine that performs real-time queries through a variety of interfaces including SOAP, XML, REST, and SQL. Support for tools such as Couchbase, MySQL, Kafka, and MariaDB enable real-time data ingestion for live stream IoT workloads. The platform also leverages Tensorflow to perform CPU-based Neural Networks Learning, giving you the simplicity of ECL and the power ofTensorflow.
Built in libraries include scripts for information extraction, profiling, cleaning, normalization, and analytics. Our Machine Learning library works efficiently in a parallel distributed environment, so you can execute Machine Learning algorithms without moving data to a new platform. Seamless integration makes it easy to deliver the flexibility yourclients need.
Our platform offers robust connectivity options and integrates with a number of third-party solutions to make data lake management as easy and seamless as possible. ECL provides a fast, powerful coding experience from ingestion to information delivery. ECL is an easy-to-learn, advanced, and flexible declarative language that was initially developed for complex data scenarios more than 20 years ago and has been tested and refined continuously ever since.READY TO DIVE IN?
