MariaDB ColumnStore Distributed User Defined Aggregate Functions

MariaDB ColumnStore 1.1 introduces the Distributed User Defined Aggregate Functions (UDAF) C++ API. MariaDB Server has supported UDAF (a C API) for a while, but now we have extended it to the ColumnStore Engine.

These functions can also be used as Analytic (Window) functions just like any built in aggregate. You should have a working understanding of C++ to use this API.

Atomic Compound Statements

Recently, we had a discussion about a hypothetical feature, "START TRANSACTION ON ERROR ROLLBACK", that our users would find very useful. It would allow sending several commands to the server in one batch (a single network packet), and let the server handle the errors. This would combine efficient network use, and atomic execution. It turns out that it is already possible to do this with MariaDB, albeit with a slightly different syntax.
