HybridDB for PostgreSQL instances are categorized into the following type families:

  • High-performance: The name of this type family starts with gpdb.group.segsdx. This type family features a better I/O capability that secures higher performance.

  • High-capacity: The name of this type family starts with gpdb.group.seghdx. This type family features a larger and more affordable space to meet higher storage demands.
