Add Partition is an orchestration component that lets users define the Amazon S3 directory structure for partitioned external table data. This works by attributing values to each partition on the table. On Amazon S3, a single folder is created for each partition value and is named according to the corresponding partition key and value. For example, the partition value for the key Salesdate might be 2016-01-17. A directory would then be created on S3 named Salesdate=2016-01-17 containing this partition’s data.
This component only adds physical partitions on Amazon S3.
The table itself must already have partitions defined in the Create External Table component.
