TokuDB® v5.2 is a drop-in replacement for InnoDB that scales MySQL® from GBs to TBs while improving insert speed, query performance, compression, and online schema flexibility. Uses standard SQL and supports ACID and MVCC.

In my post on June 18th, I explained why the semantics of normal ad-hoc insertions with a primary key are expensive because they require disk seeks on large data sets. I previously explained why it would be better
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…
Continuing in the theme from previous posts, I’d like to examine another case where we can eliminate all disk seeks from a MySQL operation and therefore get two orders-of-magnitude speedup. The general outline of these posts is:
B-trees do…
In my last post, I discussed how fractal tree data structures can be up to two orders of magnitude faster on deletions over B-trees. I focused on the deletions where the row entry is known (the storage engine…
In part 1, I discussed why having many disk seeks are bad (they slow down performance), and how fractal tree data structures minimize disk seeks on ad-hoc insertions, whereas B-trees practically guarantee that disk seeks are performed on…
