Change data partitioning
When replicating to a Google Cloud Storage target, for each of the source tables, a directory is created under the specified target directory. When Change Data Partitioning is enabled, an additional sub-directory is created under the corresponding table directory. The data and metadata (when the metadata option is enabled) files are located in the partition subdirectory, as in the following example:
{Target Directory}
{Table_1}
{Partition_1}
Data files
DFM files
{Partition_2}
Data files
DFM files
{Partition_3}
Data files
DFM files
{Table_2}
{Partition_1}
Data files
DFM files
{Partition_2}
Data files
DFM files
{Partition_3}
Data files
DFM files
Information about the partitions is written to the attrep_cdc_partitions Control Table. For information about this table, see Change data partitions.
