This enables virtual columns to cache their outputs in case they are called multiple times on the same underlying row. This is common for numeric selectors, where the common pattern is to call isNull() and then follow with getLong(), getFloat(), or getDouble(). Here, output caching reduces the number of expression evals by half. -- This is an automated message from the Apache Git Service.
