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.
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.
In Vertica version 8.0.0, we added integration for Apache Spark through our Vertica Connector for Apache Spark. This is a fast parallel connector that allows you to transfer data between Apache Spark and Vertica.
