PostgreSQL database migration is a complex task, especially when dealing with time-series data. To simplify this process, Timescale introduced the live migration tool, which has been further improved for enhanced functionality and performance. The team expanded migration paths, added support for generated columns, table-data filtering, and resume capability, and made several reliability improvements. Performance optimizations include batch processing for single-row inserts, PostgreSQL pipeline mode, and parallel processing capabilities. These enhancements aim to make database migration faster, more reliable, and less disruptive to ongoing operations.
