Major performance improvements are here for Fabric Environment! Environment publishing is now up to 2.5x faster, and session startup speeds have improved by up to 3x, delivering a smoother and more reliable experience for developers.
What's Improved
- Lightning-fast publishing for JAR and Python files - What used to take minutes now completes in under a minute, giving you near-instant turnaround for custom JAR or .py installations.
- Faster publishing for Python packages - Publishing Python packages is now up to 2.5x faster for public and custom packages.
- Significantly reduced Spark session startup times - Spark sessions attached to environments with Python libraries now start up to 70% faster with both live sessions and on-demand sessions, providing a more predictable and responsive experience for both interactive and production workloads.
What's Next?
New library installation mode for lightweight packages and quick iteration is around the corner. Stay tuned for even more enhancements to Environments and library management.
