PROFILE
Priyanshi Gupta
Worked extensively on the yugabyte/yb-voyager repository, delivering robust data migration tooling for PostgreSQL and YugabyteDB environments. Focused on backend development and CLI engineering, the work included building features for live and offline migrations, schema analysis, and conflict detection, with careful attention to data integrity and operational safety. Leveraged Go and SQL to implement resumable workflows, advanced reporting, and automated testing frameworks, while integrating telemetry and configuration management for observability and reliability. Addressed complex scenarios such as partitioned tables, unique index handling, and iterative cutovers, resulting in a migration platform that supports flexible, reliable, and maintainable database transitions.

Dec 1, 2025December 2025 (2025-12) — yugabyte/yb-voyager focused on strengthening data integrity during live migrations and partitioned data handling, while upgrading the platform. Delivered three core initiatives with targeted fixes and improvements: 1) Expression-based unique indexes and conflict detection improvements, including sequential event processing for such indexes, configurable partition strategy (--cdc-partition-strategy), propagation of leaf-partition constraints to the root, improved import logic, and tests for NULL/partial predicates. 2) Live migration robustness and data-type handling (gRPC connector, partitioned tables, and UX): LTREE support, skipping unsupported types, UDTs and arrays handling in the logical connector, validation tests, improved export messaging, clearer limitations, BYTEA streaming improvements, and increased ObjectMapper limits; added a tech-preview note for GRPC-based live migration. 3) Release upgrade and pg_parquet extension: upgraded to stable release 2025.2.0.0 and introduced the pg_parquet extension. These efforts collectively reduce migration risk, improve data fidelity across partitioned schemas, and prepare Voyager for broader data-type coverage and faster upgrades.
