Iurii Gerzhedovich commented on IGNITE-22968:
---------------------------------------------
[~lunigorn],
IGNITE 3 has even another syntax beside of set of supported functions. For
upcoming release we need to prepare documentation with list of supported
functions, but I sure that we shouldn't put into product special cases for
functions working in AI2. Also worth mentioning it's not obvious from parser
perspective that it is an unknown function.
I propose to close the ticket.
