How to run Pentaho transformations in parallel and limit executors
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.

1 You need to pass 3 rows, each with 1 field, instead of a single row with 3 fields. The number of fields must match the number of parameters of your query. So, in short, transpose your data. Either: read line as a single field then use Split field to rows or read as now and use Row normalizer Both approaches should work. Share Follow

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.
