BLOB revolution in new HQbird 2024 R2 Update 2

HQbird 2024R2u2 Introduces Breakthrough BLOB Network Performance

In the latest HQbird release (2024R2u2, version 5.0.3), significant improvements have been made to BLOB data transfer across high-latency networks like the Internet.

This optimization dramatically improves BLOB transfer speeds, bringing them on par with VARCHAR data. However, to leverage this enhancement, both server and client components must be updated to the newest version.

The performance breakthrough enables efficient cloud hosting of Firebird databases while maintaining full compatibility with traditional client applications. This advancement opens exciting new possibilities for cloud-based Firebird deployments, making remote database access substantially more practical for real-world applications.

To explore these new features in depth, D. Simonov—author of the official Firebird documentation (Language Reference and Developer Guide) and the free book "Detailed New Features of Firebird 5"—has written a comprehensive article titled "Transferring BLOBs over the wire in Firebird." (also available in PDF)
