-----------------------------------------
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).
