Automating Materialized View Maintenance with Incremental View Maintenance in PostgreSQL
What is Incremental View Maintenance (IVM)? ๐
The text discusses Incremental View Maintenance (IVM) in the context of PostgreSQL, explaining how IVM provides a method for keeping materialized views current by calculating and applying only the incremental changes. It highlights the advantages of materialized views and the limitations that IVM aims to address, including the manual update requirement and the need to reprocess the entire dataset. The pg_ivm Postgres extension is introduced as a solution for automatic maintenance, providing incremental updates to materialized views. Additionally, the text touches on Change Data Capture (CDC) and the Flink Postgres CDC Connector as methods for capturing and processing enriched data from materialized views. It also compares IVM with streaming databases, noting differences in their capabilities.
