AnalyticDB:Instance types

Choose an instance type

Select an instance type based on your workload's I/O demands and storage requirements:

• High-performance (gpdb.group.segsdx): Backed by SSD storage, this family delivers higher I/O throughput. Choose it for query-intensive workloads where read/write speed is the primary bottleneck.

• High-capacity (gpdb.group.seghdx): Backed by HDD storage, this family provides more storage per dollar. Choose it for large datasets where cost-efficient storage matters more than raw I/O performance.

To reduce storage costs further, offload data that is not involved in real-time computing to OSS-based external tables. AnalyticDB for PostgreSQL supports gzip compression for data in external storage.
