Stefan Miklosovic commented on CASSANDRA-19002:
-----------------------------------------------
The patch will consist of these parts:
in 3.0, 3.11, 4.0, 4.1, 5.0 and trunk, there will be "HintsMaker" class added
which is used for hints generation. Its behavior is logically very similar to
what CommitLogUpgradeTestMaker is currently doing. Hence we will have a way how
to generate hint files and commit logs programmatically.
Then, in 5.0 and trunk, there will be tests added into CommitLogUpgradeTest
which is already there but it covers only commit logs replay for Cassandra 3.4.
Also, in 5.0 and trunk, there will be HintsUpgradeTest added which will verify
the deserialisation of hints generated in the latest 3.0 release as well as
these in the latest 4.0 release (4.0.11 at the moment). There are 3 versions of
hint files at the moment, 1, 2, and 3. 1 is used up to 4.0 excluded, 2 is used
up to 5.0 excluded, 3 is used from 5.0 up. Hence, it does not make sense to
verify that Cassandra 5.0 can read its own hint files, we will go just with
version 1 and version 2 of hint files for 5.0 and trunk branches.
