You can repartition archived data directly in the Data Vault to improve query performance and to free resources. You can also repartition data to change the number of rows in data files.
You use one table column as the partition key. The partition key column can include any datatype except for LOB datatypes. The Data Vault uses the range partitioning method to repartition data.
