… VTL templates - Add resolver optimization to reduce unnecessary S3 uploads during push - Compare VTL templates between current and new builds to detect changes - Reuse existing S3 deployment paths for unchanged resolver templates - Add --skip-unchanged-resolvers flag to amplify push command - Preserve deployment root keys for unchanged nested stack resources Performance improvement for AppSync APIs with many resolvers where only a subset have changed. This optimization can significantly reduce deployment time by avoiding re-uploading identical VTL mapping templates to S3. The optimization process: 1. Compares request/response mapping templates between builds 2. Identifies unchanged AppSync function configurations 3. Preserves existing S3 locations for unchanged templates 4. Only uploads modified resolver templates This change is backward compatible and opt-in via the --skip-unchanged-resolvers flag.
