> When calculating the schema compatibility field aliases are not taken into
> account to calculate the end result, for example:
> The compatibility result for following schemas (writer schema_v1 and reader
> schema_v2) must be {*}Ok(()){*}, but it is not the case
>
> {code:js}
> let schema_v1 = Schema::parse_str(r#"
> {
> "type": "record",
> "name": "Conference",
> "namespace": "advdaba",
> "fields": [
> {"type": "string", "name": "name"},
> {"type": "long", "name": "time"}
> ]
> }"#)?;
> let schema_v2 = Schema::parse_str(r#"
> {
> "type": "record",
> "name": "Conference",
> "namespace": "advdaba",
> "fields": [
> {"type": "string", "name": "name"},
> {"type": "long", "name": "date", "aliases" : [ "time" ]}
> ]
> }"#)?;
> {code}
>
> Then the compatibility gives the following *error*
> {code:js}
> assert!(SchemaCompatibility::can_read(&schema_v1, &schema_v2).is_err());
> // Incompatible schemata! Field 'date' in reader schema must have a default
> value"
> {code}
> The error must not happen because *date* has the *time* alias
