Yury Gerzhedovich commented on IGNITE-11434:
--------------------------------------------

[~vozerov], [~tledkov-gridgain], What reason to have PRIMARY_KEY column? We can have complex
PK, when few columns will be part of PK. Moreover if we will have we don't know position the
column in the PK.  May be such information should be placed in INDEX view?
