Kirill Tkalenko updated IGNITE-17211:
-------------------------------------
Description:
*Problem*
If the polymorphic configuration is nested (sub), then when trying to create an
instance of the configuration, we will receive the error *Polymorphic
configuration type is not defined*, since the type of the polymorphic
configuration is not known and can be changed in the future, in order to get
around this limitation, you have to set the default type, which may not always
be correct.
*Stack trace example:*
{noformat}
Caused by: java.lang.IllegalStateException: Polymorphic configuration type is
not defined:
org.apache.ignite.configuration.schemas.table.ColumnDefaultConfigurationSchema.
See @PolymorphicConfig documentation.
