@@ -21,6 +21,7 @@ Handing raw customer data to a third party introduces two long-term headaches:
 
 1. Governance and compliance risk – once data leaves your perimeter, you lose direct control over how long it’s stored, where it resides, and who can see it. A single mis-configuration or model-training clause could violate GDPR, HIPAA, or internal policy.
 2. Technical debt – the day you need to swap providers, migrate regions, or delete a customer record, you discover tight coupling in schemas, pipelines, and security controls that were never designed for portability.
+3. Technical debt - having to synchronize data between multiple vendors and your own systems, which can lead to data inconsistencies and increased complexity.
 
 ## Best practices: bring the AI to the data, not the data to the AI

 | Data lineage | OpenLineage | A vendor-neutral API for emitting and collecting lineage events from Spark, Airflow, dbt, BigQuery, and more. Lets you trace every model back to the exact inputs that produced it. |
 | Zero-copy data sharing | Delta Sharing (REST), Iceberg REST Catalog, Arrow Flight SQL | Instead of emailing CSVs, expose live tables through open protocols. Recipients query directly—Spark, Pandas, BI tools—while you keep full revocation and audit control. Delta Sharing is the first open REST protocol for this purpose; Iceberg’s REST catalog spec and Arrow Flight do the same for metadata and high-speed transport. |
