AnalyticDB for PostgreSQL - Definition of Instance Types Changed
Target customers: data warehousing, big data, data analysis, and database users, and users in the government, finance, retail, and Internet industries. Features released: an AnalyticDB for PostgreSQL instance is now composed of multiple nodes instead of multiple computing groups. This definition change simplifies the instance types in the massively parallel processing (MPP) architecture and conforms to the standard of database clustering. A node contains only one MPP data partition, which simplifies the selection and use of MPP clusters. A computing group may contain multiple MPP data partitions.
