Storage for Analytics services on GCP
Analytics services on GCP feature object storage for columnar data, SSD-backed storage for transactional data, and data-at-rest encryption.
ColumnStore Data Warehouse
ColumnStore Data Warehouse stores columnar data on object storage through Google Cloud Storage (GCS). Object storage is not pre-allocated. It scales automatically with your needs.
By default, 100GB of transactional storage is provisioned at time of service launch.
MariaDB SkySQL features transparent data-at-rest encryption. This feature is not customer-configurable. Google's default encryption is used for transactional storage.
Transactional Storage Type
On GCP, Zonal SSD Persistent Disk is used.
