yong yang commented on FLINK-34001:
-----------------------------------
tb1 join tb2(dim table);
The amount of data in tb1 is very large, but only a small part of the data can
be matched in tb2;
if use lookup join, You can't avoid caching large amounts of data, nor can you
avoid the stress that a large number of queries put on dimension tables;
so I want to do this using a two-stream join, with the dimension table using
the flinkcdc method;
