It's a bit odd to pick out the restart stress portion of the test and only run that bit with transactions.
The approach for compaction is to have a top level set of repeater_kwargs, and two different test cases (compacted vs. non) -- can we do the same for transactions? Maybe rather than each feature independently, we should have just two variants of the test: vanilla (no compaction or transactions) and "fully loaded" (compaction, transactions enabled).
I think that'll be useful in identifying which failures result from issues in the primary data path, vs. which ones relate to particular optional features.

Not sure where you're running this in development, but would be good to try it on i3en.6xlarge instances. The nightly runs are on i3en.xlarge for cost, but that's only ~10k partitions, the i3en.6xlarge instances will get you up to the When you try the version with+without transactions, it may be that we get an interesting result in terms of what the hard partition limit can be with transactions on vs. off. |

This PR extends the many_partitions test to use transactions in background traffic during a restart stress test. Not sure if this is the best place to insert transactions into our scale tests. However, I thought it'd be a good starting place for a discussion about where adding in transactions would be appropriate.
This PR requires redpanda-data/kgo-verifier#16 to be merged for the changed test to pass.
