A very high level comment: I see that you are renaming the module presto-sql-function to presto-function-namespace-managers and adding the function namespace manager directly to this module. If you are planning to do this, you probably want to introduce subdirectories to organize the code rather than keep them all under .../sql-function.

@rongrong Ready for another pass.
Made a few improvements in the 3rd commit and will merge into the 2nd commit before merging.

Use annotation to pre-define all <function-namespaces-table> and <sql-functions-table> without requiring String to be passed as parameters.
Use module to create FunctionNamespaceManager in test, so that the module is tested as well.
Update some config names and default values.

"executing functions" is not new and it's not something "allowed" by function namespace managers.

I intend to say "resolving functions"

Contributor

rongrong Feb 7, 2020

resolving function is also not introduced by function namespace manager though.

The function namespace part is very understandable. Looks good. Couple of minor suggested changes but overall seems very clear.

When we're saying a function namespace manager, we're referencing an instance, not a type of function namespace manager. So, maybe, I should just say each Each function namespace manager....

For the release note, I'd mention "function namespace manager" and refer to the documentation added.
