Core Module Patterns - ECS Variation Summary cache only
Question
Architecture

Hi everyone,

I just watched this video from the Architecture Patterns in OutSystems course: https://learn.outsystems.com/training/journeys/architecting-sustainable-apps-648/core-module-patterns/o11/677

The video describes a pattern to cache only summary data, but where exactly is this cached data stored? Does it refer to local replicas or other entities?


Thanks in advance!

Hi @Katsuaki Kurahashi ,

this whole lesson is about core module patterns.  When they say 'cache' or 'local replica' in this lesson, they mean a normal OutSystems entity holding actual data in an OutSystems database.

In case of the pattern "Summary cache only", it means that the cache datamodel in OutSystems will have fewer attributes (and maybe even fewer entities) than the tables and columns that exist in the external system.

Thank you for the detailed explanation! Your clarification about the cache and local replicas in the context of core module patterns was very helpful. I now understand how the “Summary cache only” pattern works in terms of data modeling.

Thanks again for your assistance!

Best regards,

Katsuaki Kurahashi
