MariaDB has had support for histograms as part of Engine Independent Table Statistics since 10.0. As part of Google Summer of Code (MDEV-21130), Michael Okoko, together with his mentor Sergey Petrunia, have implemented a new format (using JSON) for histograms that significantly improves the accuracy and flexibility of histograms. For those just interested in the feature details, you can skip to the “New format”, however if one is unfamiliar with the purpose of histograms, read on.
Why statistics are needed
Histograms are important for queries where the WHERE clause uses columns that are not indexed.

MariaDB has been using a pluggable storage engine architecture for a long time and whilst this means great flexibility in choosing and managing the right storage engines for specific use cases, it also means they are easier to develop and therefore there’s an expectation that more engines will be created.
More storage engines means the MariaDB Server itself needs to be as flexible as possible to accommodate all sorts of functionalities that storage engines may need. One area where the MariaDB Server proved to be not that welcoming was in making available all the compression libraries needed by storage engines.

Natural sort order is the ordering of strings in alphabetical order, while numbers are treated as numbers. This understanding of sorting is closer to human comprehension than to a machine. You can find an example of this feature in the Windows file manager. There the files are sorted in natural order. Try to create four folders “b1”, “a11”, “a2”, “a1”.
There are several programming languages which have natural sort. In PHP it is built-in function natsort, while as an third-party module in Python it is natsort, in Perl it is Sort::Naturally and in Matlab it is sort_nat.

Universally unique identifiers (UUIDs) have a common place in computing already. A 128-bit value with a text representational value and the prescription of a number of version types to ensure a uniqueness makes it an ideal data type.
After many years of the UUID datatype existing only as a feature request in MDEV-4958, slowly accumulating votes and watchers, we are pleased to announce a preview of the UUID data type. Like the INET6 data type, this uses the datatype plugin API from MariaDB 10.5.
What does the UUID data type look like?
