MDEV-7773 documents the server requirements for supporting this. We can't completely follow this since we need to be able to support distributed execution at the pm level.

Comment by David Hall (Inactive) [ 2017-05-22 ]

MDEV-7773 is for writing UDAF and possibly UDAnF in SQL. It doesn't talk about plugins or anything implemented in a lower level language.

How UDAF implemented in SQL would be handled is unclear, so how it would affect Columnstore is also an unknown.

Ah good point, yes that would definitely be out of scope in my mind.

Code complete. Changes to the test suite are in pull request #40, possibly mislabeled as MCOL-597. We're still not done with the project, as we're working on a loader and building more test suites. However, it's time to merge this into develop and get the nightlies running against it.

The code needs to be reviewed and merged into develop. Re-assign the JIRA to Ben when done if all goes well. He's working on adding stuff.

Pull Request #41 for regression tests

Comment by Andrew Hutchings (Inactive) [ 2017-08-03 ]

Review looks good. Moving to Ben as requested.
