8.0

Disabling Numeric Overflow

Prior to version 8.0, using a column that has a numeric data type with the functions SUM, SUM_FLOAT, or AVG could result in numeric overflow. Now, you have the ability to turn-off numeric overflow and add implicit precision to your numeric data types.

Post-upgrade Tasks for Saving Catalog Space

When you upgrade to 7.2 and later, not only can you take advantage of the new features, you can perform tasks to save substantial space in your Vertica catalog.
