> Key: IGNITE-18969
> URL: https://issues.apache.org/jira/browse/IGNITE-18969
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Maksim Zhuravkov
> Priority: Minor
> Labels: calcite3-required, ignite-3
> 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).
