Fractal Tree can also lessen the wear and tear on SSDs, the company has claimed. This factor might be an important for organizations considering the use of SSDs in the data center. Although they can outperform standard disk drives, SSDs can wear out more quickly if subjected to intense writing and rewriting of data.
Thanks to how Fractal Tree aggregates and rebalances data, TokuDB writes to flash memory in much larger blocks than a typical database engine. This approach reduces write amplification, in which the same data is rewritten to disk multiple times.
This latest release of TokuDB comes with a number of additional improvements that have given the company confidence in pitching the database as being optimized for SSDs. These updates include refinement of the locking and latching mechanisms, better parallelism on reads, and performance improvements in point and range queries across both primary and secondary indexes, according to Lawrence Schwartz, TokuDB vice president of marketing.
TokuDB can be licensed for US$2,500 per 100GB, per year. It is available for up to 50GB for free evaluation and proof of concept projects.
