I’m concerned that very little news has been heard from the TokuDB development team. According to the tokudb-engine Github page, no commits have been made since the 1st of September 2015. Is it still being developed?
In MySQL 5.7, InnoDB has been enhanced to support very useful features including a JSON datatype, Spatial Indexing and Indexable Virtual Columns. However, InnoDB still does not support online addition/removal of columns - something that TokuDB handles brilliantly. This has greatly eased maintenance work in our production systems. InnoDB has also added support for page compression. Haven’t had a change to test it yet, but I doubt it would perform as well as TokuDB’s as InnoDB does not utilise TokuDB’s fractal tree indexes.
I am hoping to find out the TokuDB team’s plans for implementing the following features:
Indexable Virtual Columns
Official Galera support
TokuDB and fractal tree indexes are such great technology and add so much value to MySQL. It would really suck if they were not allowed to reach their full potential.
