Stanislav Lukyanov commented on IGNITE-13364:
---------------------------------------------
The patch LGTM! I've started a devlist discussion on this since this has a
compatibility impact and probably should be discussed before merging.

> We need to improve how inline size is calculated by default for
> variable-length types.
> Currently if a varlength type is encountered inline size just defaults to 10,
> which is almost always not enough.
> A more sensible behavior would be the following:
> 1. Add a fixed default to the inline size calculation for every
> variable-length type. For example, if the default inlined size for a string
> is 10 then an index like (INT, VARCHAR, VARCHAR, INT) should have inline size
> default as 5 + 10 + 10 + 5 = 30 (5 for each int, 10 for each string).
> 2. Add special support for VARCHAR_FIXED - if a VARCHAR has known length then
> that length is used for inline size calculation
