Logical replication with pglogical | ODP | Databases | Computer Software and Applications
This document discusses logical replication with pglogical. It begins by explaining that pglogical performs row-oriented replication and outputs replication data that can be used in various ways. It then covers the architectures of standalone PostgreSQL, physical replication, and logical replication. The rest of the document discusses key aspects of pglogical such as its output plugin, selective replication capabilities, performance and future plans, and examples of using the output with other applications. - Download as a ODP, PPTX or view online for free
