Jacek Lewandowski updated CASSANDRA-19479:
------------------------------------------
Description:
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)
Additionally, the equals method in TupleType and UserType was fixed to be
symmetric. Previously, comparing two values gave a different outcome when
inverted.

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 test were implemented under CASSANDRA-14476, we need to verify that in that
certain upgrade paths.
> Provide tests for type compatibility between 4.1 and 5.0
