Hotel source data is mutable in the past, so an append-only pipeline drifts away from the PMS without anyone noticing until month close. A practical guide to room-night grain, bitemporal modeling with Apache Iceberg, PMS ingestion, guest data scope, and file physics at hotel volumes.
Most Salesforce AWS integrations don't fail loudly, they drift. This guide covers the four integration paths between Salesforce and AWS, when to use each, the silent failure mode hiding in every one of them, and the reconciliation job you have to build yourself.
The AWS Glue SAP OData connector demos beautifully and then drifts. A practical look at delta token invalidation, deletes that never delete, partitioning limits on ODP entities, and the licensing line between ODP-RFC and ODP-OData.
