| Technical Architect at a tech services company with 11-50 employees | 4.0 | I use Amazon QLDB for transaction management due to its fast querying and version maintenance. It's easier than traditional blockchain but needs better data import capabilities and more instances. I also use MongoDB for data aggregation. |
