BatchSize implements Transformation
Read onlyYes
FinalYes
Sets batch size for DataFrame.
Small batch size can be useful when processing large data sets since only one row is processed at a time. This means that while processing large data sets, memory usage is kept low.
Normally flow allows to use batch size -1 (which means no batches) but it defeats the purpose of using this transformation on Data Streams.
