Function and type namespaces about trino

[jerryleooo]

@martint does this mean that if when we use function with namesapce, like druid.func1(col1), then it will be Druid to execute the func1(col1)(function pushdown) instead of Trino?

Any plan for this feature? @martint @dain

@jerryleooo @caneGuy @l568288g This means that a catalog can provide a function under a specific name like druid.functions.func1(col1). There is a PATH that can be modified by the end users so that functions do not need to be fully qualified (and there is a system level default PATH). This is like any other function, but the catalogSchema should be set to the catalog and schema of the function... but I was just looking at the code and this isn't implemented, so this wil need some follow up work
