#### Problem
|
|
The idea of this test group is to simulate issues that can arise during rolling upgrade/downgrade.
|
|
|
|
#### Implementation
|
|
In this test group, the docker compose cluster is launched with services on different versions.
|
|
The docker image for the previous version is built by downloading the previous version druid tar.
|
|
Currently, the case where Coordinator and Overlord is on the previous version is tested.
|
|
|
|
#### Test coverage
|
|
Existing
|
|
- MSQ ingestion
|
|
- Native ingestion
|
|
- Stream ingestion
|
|
- Querying
|
|
|
|
Pending
|
|
- Compaction
|
|
|
|
#### Limitations
|
|
* `druid-testing-tools` jar is not published. The image for the previous version still uses the
|
|
extension from the current build.
|
|
This could break in case of incompatible changes in this extension.
|
|
In such a scenario the test should be disabled. However, this extension is primarily used to
|
|
test specific error scenarios and launch custom node role service (used in HighAvailability test group).
