CA DataMinder does not store each blob as a single Centera object. It groups them into clips, significantly reducing write times for event data migrated to Centera. Policy settings on the CMS determine the maximum number of blobs and KB per clip.
By default, blob files are compressed and encrypted when they are stored on the CMS. They are stored to Centera in the same format.
If multiple blobs are stored in Centera clips, CA DataMinder blob files are concatenated into a single Centera blob, referenced from the Centera clip. Blob offset and length details are stored in the clip to optimize data retrieval during event searches.
Note: CA DataMinder does not store blob files with differing trigger-defined Minimum Retention Periods in the same Centera clip.
