http://dev.mysql.com/doc/refman/6.0/en/se-falcon-features.html 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.
* 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 data files and extensions. Space within log and data files is automatically reclaimed and reused.
* 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.
