pentaho looping in a Kettle transformation Stack Overflow
One Transformation to get my data via query and the other Transformation to Loop over each row of my result Query. So this means my result set of Text files or CSV files should be 6. Next, we go to the next Transformation Execute For Every Row/Loop. Here we can see that we are Getting our Copied Rows Set by using the Get Rows from Result and.
Pentaho Hangout Building Data Integration and Transformations using
Pentaho Data Integration (PDI) is a powerful open-source ETL tool that users can use to extract, transform, and load data from various sources into a target system. In PDI, a typical ETL workflow consists of Jobs and Transformations. A Transformation represents the data transformation part of an ETL workflow, and performs data manipulation.

Using Transformation executors The Transformation Executor is a PDI step that allows you to execute a Transformation several times simulating a loop. The executor receives a dataset, and then executes. - Selection from Learning Pentaho Data Integration 8 CE - Third Edition [Book]
How to run Pentaho transformations in parallel and limit executors
Modelling by Virgin Hyperloop One in 2016 estimated a per-mile cost of $84 to $121 million for a cut-down 107-mile Bay Area project. This compares to a projected cost of $178 million per mile for.
Run Time Optimisation Of Pentaho PDI Transformation Programming
A hyperloop, as you may have heard, is a super speed ground-level transportation system in which people could travel in a hovering pod inside a vacuum tube at speeds as high as 760 mph (1220 km/h), just shy of the speed of sound. Virgin's system includes magnetic levitation, much like the technology used in advanced high-speed rail projects in.

Transformation Steps. A step is one part of a transformation. Steps can provide you with a wide range of functionality ranging from reading text-files to implementing slowly changing dimensions. This chapter describes various step settings followed by a detailed description of available step types. The following topics are covered in this.
Metadata Injection Using Pentaho TatvaSoft Blog
As you build a transformation, you may notice a sequence of steps you want to repeat. This sequence can be turned into a mapping. Just like the Mapping step, you can use the Simple Mapping (sub-transformation) step to turn the repetitive, re-usable part of a transformation into a mapping.. Compared to the Mapping step, the Simple Mapping (sub-transformation) step accepts one and only one input.

Pentaho Data Integration
HyperloopTT is currently testing its system on a track that's one-fifth of a mile at its research and development center in Toulouse, France. Its first commercial deployment will be in the United Arab Emirates, with a six-mile system in Abu Dhabi that's expected to break ground later this year. The world's first commercial hyperloop.
Concept of Loops in Pentaho IT Talkers
Allowing loops in transformations may result in endless loops and other problems. Loops are allowed in jobs because Spoon executes job entries sequentially. Make sure you don't build endless loops. This job entry can help you exit closed loops based on the number of times a job entry was executed. Mixing Rows-Trap Detector

The biggie. Over a staggering 1,152 miles from Cheyenne to Houston, this route would serve 17.7 million people and connect up the Rocky Mountains. A journey that would normally take 17 hours by.
How to run Pentaho transformations in parallel and limit executors
Trans-Loop Transformation: Here, we need to increment that Loop (NEW_LOOP) by 1 and set the same variable which is NEW_LOOP. Simple Evaluation: Here, we are evaluating NEW_LOOP variable with 2. You can change this value based on your project needs. Here, this loop will run two times.If NEW_LOOP variable reaches value 2, then it will abort the job.
Create a Transformation in Pentaho
The Job Executor is a PDI step that allows you to execute a Job several times simulating a loop. The executor receives a dataset, and then executes the Job once for each row or a set of rows of the incoming dataset. To understand how this works, we will build a very simple example.
data integration Loops in Pentaho is this transformation looping
The Transformation Executor step allows you to execute a Pentaho Data Integration (PDI) transformation. It is similar to the Job Executor step, but works with transformations. Depending on your data transformation needs, the Transformation Executor step can be set up to function in any of the following ways:
Concept of Loops in Pentaho IT Talkers
Generally for implementing batch processing we use the looping concept provided by Pentaho in their ETL jobs. The loops in PDI are supported only on jobs (kjb) and it is not supported in transformations (ktr). Make data easy with Helical Insight. Helical Insight is the world's best open source business intelligence tool.
