CMN_2020 Warning: If the master and detail pipelines of a sorted Joiner transformation are from the same source, the Integration Service cannot determine how fast it will process the rows in each pipeline. As a result, the cache size estimate may be inaccurate.
CMN_2021 Warning: Increase the data cache size if the sorted Joiner transformation processes master rows that share the same key. To determine the new cache size, divide the existing cache size by 2.5 and multiply the result by the average number of master rows per key.
