In this Skyward Data episode, Vince Re, CTO of VirtualZ and the original architect behind much of today’s mainframe innovation, walks through a live demo of PropelZ™ in its new Incremental Mode — showing how it delivers faster, smarter data movement without reprocessing entire files.
Over seven minutes, Vince demonstrates how PropelZ captures, transforms, and updates VSAM data directly into a modern relational database, automatically handling complex mainframe structures such as packed decimals, binary fields, and floating-point data.
🔹 Viewing a real VSAM dataset in IBM File Manager (76,000+ airport records)
🔹 Understanding COBOL copybook metadata and schema mapping
🔹 Running PropelZ with the Incremental option
🔹 Creating and populating MySQL tables with full index generation
🔹 Making live record edits and running a lightning-fast incremental update
🔹 Verifying changed records instantly in SQL
PropelZ Incremental Mode pinpoints and updates only what’s changed — reducing processing time by up to
20× while preserving complete data integrity.
