Falcon support is not available in the standard MySQL 5.1 release. Falcon is available only in a specially forked release of MySQL 5.1. Information is provided here for evaluation purposes only.
Falcon has been specially developed for systems that are able to support larger memory architectures and multi-threaded or multi-core CPU environments. Most 64-bit architectures are ideal platforms for the Falcon engine, where there is a larger available memory space and 2-, 4- or 8-core CPUs available. It can also be deployed within a standard 32-bit environment.
The Falcon storage engine is designed to work within high-traffic transactional applications. It supports a number of key features that make this possible:
True Multi Version Concurrency Control (MVCC) enables records and tables to be updated without the overhead associated with row-level locking mechanisms. The MVCC implementation virtually eliminates the need to lock tables or rows during the update process.
Flexible locking, including flexible locking levels and smart deadlock detection keep data protected and transactions and operations flowing at full speed.
Optimized for modern CPUs and environments to support multiple threads allowing multiple transactions and fast transaction handling.
Transaction-safe (fully ACID-compliant) and able to handle multiple concurrent transactions.
Serial Log provides high performance and recovery capabilities without sacrificing performance.
Advanced B-Tree indexes.
Server enforced referential integrity ensures data validity at all times.
Data compression stores the information on disk in a compressed format, compressing and decompressing data on the fly. The result is in smaller and more efficient physical data sizes.
Intelligent disk management automatically manages disk file size, extensions and space reclamation.
Data and index caching provides quick access to data without the requirement to load index data from disk.
Implicit savepoints ensure data integrity during transactions.
