AWS Redshift database. AWS Redshift is one of the most efficient, flexible, accessible, and popular databases, so we are going to use it as the main repository for our data. The first thing to do is to create a Redshift cluster for the database. After that, you will have to define the cluster and database parameters:
Optional string value denoting what to interpret as a NULL value from the file. Note that this parameter is not properly quoted due to a difference between redshift’s and postgres’s COPY commands interpretation of strings. For example, null bytes must be passed to redshift’s NULL verbatim as '\0' whereas postgres’s NULL accepts '\x00'.
