Load a Large CSV into Vertica

Here's an efficient way to load a dataset into Vertica by splitting it up into multiple pieces and then parallelizing the load process.

Note that this only makes sense if your Vertica cluster is a single node. If it's running more nodes, there are definitely more efficient ways of doing this.

For this example, the large CSV file will be called large_file.csv. If your file is under 1GB, it probably makes sense to load it using a single COPY command.

Dear Client:

We are writing to share with you important information about a security compromise involving a database containing some of your personal information, as well as steps we are taking in response, and the resources we are making available to you.

What Happened

Federal law enforcement officials recently informed us that they’ve been investigating cybersecurity crimes involving the theft of information from Scottrade and other financial services companies. We immediately initiated a comprehensive response.

Based upon our subsequent internal investigation coupled with information provided by the authorities, we believe a list of client names and street addresses was taken from our system. Importantly, we have no reason to believe that Scottrade’s trading platforms or any client funds were compromised. All client passwords remained encrypted at all times and we have not seen any indication of fraudulent activity as a result of this incident.
