The number of key combinations is more than expected
We are building a warehouse using SSIS. I am doing an aggregation and I received the following message `The Aggregate transformation has encountered 2000037 key combinations. It has to re-hash data because the number of key combinations is more than expected. The component can be configured to avoid data re-hash by adjusting the Keys, KeyScale, and AutoExtendFactor properties` It did not write the output, and **most disturbingly**, it did not throw any exceptions. What is going on here? How do I fix this?
