Tokutek is pleased to announce immediate availability of TokuDB for MySQL, version 4.0. It is designed for continuous querying and analysis of large volumes of rapidly arriving and changing data, while maintaining full ACID properties.
New in TokuDB v4.0 is our multi-threaded Fast Loader. Capable of utilizing all available CPU cores, the Fast Loader greatly accelerates creating a new index or initializing a database with a bulk load. On an 8 core machine, loading operations speed up by over 4x and with 16 cores the acceleration is even greater.
Other improvements in v4.0 include:
- Shorter Logfiles – The logs needed for ACID transactions are now considerably
smaller. In addition to saving disk space, smaller logs means faster recovery in many cases.
- Faster Logfile Reclamation – When a transaction commits, the space associated with logging for that transaction is reclaimed more quickly. This helps keep disk space requirements to a minimum.
- Support for READ COMMITTED isolation level – Fulfills a very popular customer request.
This new release builds on TokuDB’s unique combination of capabilities:
- 10x-50x faster indexing for faster querying
- Full support for ACID transactions
- Short recovery time (seconds or minutes, not hours or days)
- Immunity to database aging to eliminate performance degradation and maintenance headaches
- 5x-15x data compression for reduced disk use and lower storage costs
Because of its high indexing performance and transaction support, TokuDB is well suited to Web applications that must simultaneously store and query large volumes of rapidly arriving data, including:
- Logfile Analysis
- High-speed Webcrawling
- Real-time clickstream analysis
- Social Networking
- eCommerce Personalization
