The Aggregate transformation has encountered %1!d! distinct values while performing a "count distinct" aggregation on "%2!s!". The transformation will re-hash data because the number of distinct values is more than expected. The component can be configured to avoid data re-hash by adjusting the CountDistinctKeys, CountDistinctKeyScale, and AutoExtendFactor properties.
