> This is a part of CASSANDRA-14476 - we should verify whether the type
> compatibility matrix is upgradable from 4.0 and 4.1 to 5.0, and if not, fix
> the remaining issues.
> The implemented tests verify the following:
> - assumed compatibility between primitive types
> - equals method symmetricity
> - freezing/unfreezing
> - value compatibility by using a serializer of one type to deserialize a
> value serialized using a serializer of another type
> - serialization compatibility by serializing a row with a column of one type
> as a column of another type for simple and complex cells (multicell types)
> - (comparison) compatibility by comparing serialized values of one type using
> a comparator of another type; for multicell types - build rows and compare
> cell paths of a complex type using a cell path comparator of another complex
> type
> - verify whether types that are (value/serialization/comparison) compatible
> in a previous release are still compatible with this release
> - store the compatibility matrix in a compressed JSON file so that we can
> copy it to future releases to assert backward compatibility (similar approach
> to LegacySSTableTest)
> - verify that type serializers are different for non-compatible type pairs
> which use custom comparisons
> Additionally:
> - the equals method in {{TupleType}} and {{UserType}} was fixed to be
> symmetric. Previously, comparing two values gave a different outcome when
> inverted.
> - fixed a condition in comparison method of {{AbstractCompositeType}}
> - ported a fix for composite and dynamic composite types which adds a
> distinct serializers for them so that the serializers for those types and for
> {{BytesType}} are considered different; similar thing was done for
> {{LexicalUUIDType}} to make its serializer different to {{UUIDType}}
> serializer (see
> https://the-asf.slack.com/archives/CK23JSY2K/p1712060572432959)
> - fixed a problem with DCT builder - in 5.0+ the {{DynamicCompositeType}}
> generation has a problem with inverse alias-type mapping which makes it
> vulnerable to problems when the same type has two different aliases
