Nikolay Izhikov commented on IGNITE-6055:

[~vozerov] I don't get it.

Can you name the ticket I should wait for?
How my PR depends on it?

I think my PR is correct and solves the ticket. Isn't it?

> We should support {{CHAR(X)}} and {{VARCHAR{X}} syntax. Currently, we ignore it. First,
it affects semantics. E.g., one can insert a string with greater length into a cache/table
without any problems. Second, it limits efficiency of our default configuration. E.g., index
inline cannot be applied to {{String}} data type as we cannot guess it's length.
