[jira] [Created] (IGNITE-18969) Sql. Implement of leastRestrictiveType for custom data types.

Maksim Zhuravkov created IGNITE-18969:
-----------------------------------------

             Summary: Sql. Implement of leastRestrictiveType for custom data types.
                 Key: IGNITE-18969
                 URL: https://issues.apache.org/jira/browse/IGNITE-18969
             Project: Ignite
          Issue Type: Bug
          Components: sql
            Reporter: Maksim Zhuravkov
             Fix For: 3.0.0-beta2


The current implement of IgniteTypeFactory::leastRestrictiveType returns the first custom data type it encounters, which is obviously not correct.

Add generic rules on how `leastRestrictiveType` should work for some custom data type (e.g. when a type has precision it possible to choose such, when type do not have precision, etc).
