What is tokuzilla?

Tokuzilla, also known as TokuDB, was a high-performance, write-optimized, compressed storage engine for MySQL and MariaDB. It was specifically designed to handle large datasets and high write loads efficiently. Fusion-io (later acquired by SanDisk, then Western Digital) originally developed it.

Here's a breakdown of key aspects:

• Architecture: Tokuzilla used a Fractal Tree index structure instead of the traditional B-tree. This data structure significantly improves write performance by batching writes and reducing index fragmentation. Learn more about Fractal%20Tree%20indexes.

• Compression: It offered excellent data compression, often achieving compression ratios of 50% or higher, resulting in reduced storage space requirements.

• Write Optimization: Tokuzilla was highly optimized for write-intensive workloads, making it suitable for applications like logging, event tracking, and time-series data.

• OLTP & OLAP: While primarily designed for OLTP, its compression and indexing made it somewhat suitable for certain OLAP use cases as well.

• ACID Compliance: Tokuzilla was fully ACID-compliant, ensuring data integrity and reliability.

• Support & Discontinuation: Western Digital discontinued commercial support for Tokuzilla in 2015. Consequently, it is considered deprecated and generally not recommended for new projects.

• Potential Alternatives: Due to Tokuzilla's deprecation, various alternatives exist depending on specific requirements. Options include other storage engines like InnoDB (with optimizations), RocksDB, and even specialized time-series databases.

• Considerations: When choosing an alternative to Tokuzilla, carefully consider your workload characteristics (read/write ratio, data size, etc.) and select a storage engine or database that best suits your needs.
