Unified YAML gets first-class migration and schema tooling, plus streaming execution metrics and Kafka sink upgrades.

Unified YAML Format & Migration

  • Migration tooling: Automated migration script and guide for legacy plans to unified YAML (Migration guide)
  • Unified YAML parsing: Detection and conversion pipeline to load unified configs alongside legacy plans (Configuration guide)
  • Schema validation: JSON schema for IDE autocomplete and validation of unified YAML configs (Unified YAML schema)
  • Configuration guidance: Updated unified YAML configuration and examples (Configuration guide)

Data Generation Helpers

  • String and pattern helpers: email, phone, url, uuidPattern, ipv4, ipv6, ssnPattern, creditCard
  • Date/time helpers: withinDays, futureDays, excludeWeekends, businessHours, timeBetween
  • Sequencing helpers: sequence, dailyBatchSequence, semanticVersion
  • Conditional helpers: conditionalValue, mapping
  • Array helpers: arrayWeightedOneOf, arrayEmptyProbability

Check out the Data generation helpers for more information.

Streaming & Performance

  • Kafka streaming sink: Streaming sink processor with buffering and timing metrics (Kafka guide)
  • Streaming metrics: Structured streaming performance metrics surfaced in reports and validations (HTML report, Validation)

Tooling & Examples

  • Unified YAML schema and examples: JSON schema + sample unified configs for IDE validation (Unified YAML schema)
  • Memory profiling toolkit: Load scenarios and scripts for profiling streaming workloads (Memory profiling README)

Migration Notes

Legacy YAML format remains supported, but unified YAML is recommended for new configurations and tooling support.
