Understanding the differences between Temporal tables, CDC and Time Series.

Good morning to everyone, I'm looking into Temporal Tables (TT - i.e. System/Application time versioning) but I would like to understand the differences between TTs and two other features (which appear similar in many ways) - Change Data Capture and Time Series. Are Temporal Tables (in a sense

Re: Logical Replication - Should Destination Table Columns Be Defined With Default Value
