To scale out a storage-compute coupled data warehouse with cloud SSDs, see Disk Capacity Expansion of an EVS Cluster. To scale out a storage-compute coupled data warehouse with local SSDs or a standalone system, see Scaling Out a Cluster.
Elastic specification change is only supported by storage-compute coupled and decoupled clusters that use ECSs and EVS disks. Clusters with local ECSs do not have this capability.
Performing elastic specification changes Elastic specification change is only supported by storage-compute coupled and decoupled clusters that use ECSs and EVS disks. Clusters with local ECSs do not have this capability. Stop the VM before changing the flavor.
Extreme SSD V2: ultra-high-performance SSD EVS disks dedicated for latency-sensitive mission-critical applications. Local SSD NOTE: Local SSD disks do not support disk scale-out.
Due to the decoupling of storage and compute, the EVS storage space in DWS 3.0 is half that of DWS 2.0 by default. For example, purchasing 1 TB of EVS storage provides 500 GB in DWS 3.0 for active/standby mode, compared to 1 TB in DWS 2.0.
In standalone mode, service availability is maintained through automatic ECS rebuilding, and data reliability is ensured through the EVS multi-copy mechanism. The standalone system is more cost-effective and recommended for lightweight services.

When creating a local table in the storage-compute decoupling edition with all data stored on EVS disks, make sure to explicitly set colversion to 2.0. Once a table is created, it cannot be switched from a non-V3 table to a V3 table using the ALTER TABLE syntax.
Creating an ECS Server Create an ECS by referring to the Elastic Cloud Server User Guide. The following table lists the created flavors. TPC-DS and TPC-H data sets occupy large space. For example, TPC-DS 1000X and TPC-H 1000X occupy 930 GB and 1100 GB, respectively. Therefore, select
