gpload reusable

gpload is a utility in Greenplum Database that allows users to load data from external sources into a Greenplum table. The "reusable" aspect of gpload refers to the ability to create reusable configurations that can be used to load data from multiple sources into multiple tables. This makes it easier to automate the data loading process and reduces the amount of time and effort required to set up data loading for each new source or table. Users can define a set of rules or configurations for a given data source, and then reuse those rules for subsequent data loads. This can save significant amounts of time and effort, especially for organizations that need to load large amounts of data from multiple sources into their Greenplum databases.
