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.
