We don't need to add v003tov004.sh because the change (removal of dclocal_read_repair_chance config) is in table metadata which gets handled seemlessly within cassandra upgrade when users upgrade their cassandra cluster from v3.11 to v4.0. Refactor cassandra integration tests to run on both cassandra v3.11 and v4.0. Signed-off-by: Ashmita Bohara <[email protected]>

this is a nice refactoring, makes the script much more maintainable

Do we need any documentation changes? Also, we build a certain Docker image for schema initialization, how should it be changed vis-a-vis v4? |
Good point. I will check update the documentation.
Good point. Let me check this part too. As far as I know, cqlsh from v3.11 is compatible with cassandra v4, that's how it is working in integration tests right now but we can also publish two separate images for schema-initialization for v3.11 and v4. |
I would rather make it an option to the single image, or even better if it could auto-detect v4 automatically. |

This is done because cassandra v4.0 image contains cqlsh 6.0.0 which is backward compatible with cassandra v3.x (https://pypi.org/project/cqlsh/)

Which problem is this PR solving?
Resolves #3080
Short description of the changes
We don't need to add v003tov004.sh because the change (removal of dclocal_read_repair_chance config) is in table metadata which gets handled seemlessly within cassandra upgrade (tested locally) when users upgrade their cassandra cluster from v3.11 to v4.0. So there won't be any scenario, where existing user will need migrate their data.
