Description:
This issue is a subtask of part two "Full Embedded SQL Client" of the
implementation plan mentioned in
[FLIP-24|https://cwiki.apache.org/confluence/display/FLINK/FLIP-24+-+SQL+Client].
It should be possible to declare user-defined functions in the SQL client. For
now, we limit the registration to classes that implement {{ScalarFunction}},
{{TableFunction}}, {{AggregateFunction}}. Functions that are implemented in SQL
are not part of this issue.
I would suggest to introduce a {{functions}} top-level property. The
declaration could look similar to:
{code}
functions:
- name: testFunction
from: class <-- optional, default: class
class: org.my.MyScalarFunction
constructor: <-- optional, needed for certain types of functions
- 42.0
- class: org.my.Class <-- possibility to create objects via properties
constructor:
- 1
- true
- false
- "whatever"
- type: INT
value: 1
{code}
