Hi guys,
I want to bring up a discussion about adding support of User
Defined AsyncTableFunction in Flink.
Currently, async table function are special functions for table source
to perform
async lookup. However, it's worth to support the user defined async
table function.
Because, in this way, the end SQL user can leverage it to perform the
async operation
which is useful to maximum the system throughput especially for IO
bottleneck case.
You can find some more detail in [1].
Looking forward to feedback
