Mendix applications can accumulate large sets of data originating from various sources and created for various reasons. In order to work efficiently with large datasets extra attention to performance is needed. This post will provide recommendations for speed and performance when modelling manipulations of large datasets. Use batches (limits and offsets) Batches are the execution of actions each on a set or “batch” of inputs, rather than a single input. In a microflow that manipulates large amounts of data (whether it’s changing, committing or deleting) the retrieve is not one single retrieve-action (input for the manipulation) but the processing is split in multiple retrieves each with a limit and an offset. ...
