Re: [DISCUSS] CEP-10: Cluster and Code Simulations

I tend to agree with Paulo that a major refactoring of some internal interfaces sounds like something to be explicitly avoided in a patch release. I thought this was the type of change we all agreed we should stop letting in to patch releases, and that we would attempt to release more often

Re: [DISCUSS] CEP-10: Cluster and Code Simulations

My point is that we all have different premises we are working from. I don’t think you can convince me that I am mistaken about how I interpret the word feature. The release lifecycle document we voted on is ambiguous, and we all clearly take it to mean different things. From: Jeremiah D

Re: [DISCUSS] CEP-10: Cluster and Code Simulations

No change is without risk; we have introduced serious regressions with bug fixes to patch releases. The overall risk to the release lifecycle is reduced significantly in my opinion, as we reduce the likelihood of introducing regressions, and can use the same test infrastructure across all of

Re: [DISCUSS] CEP-10: Cluster and Code Simulations

Just because it is a feature for users who are developers does not mean it is not a new feature? Adding this capability is adding new functionality to what developers can do with Apache Cassandra. How is that not a new feature? Semver has been brought up a lot in conversations around what can

Spoiler alert: I am pretty familiar with the proposal and the off-list work that has been done toward it. From my perspective, I have no qualms about putting this CEP up for a vote. Having seen the potential (and to some degree, realised) benefit of this proposal, I am convinced of its value.

Hi Benjamin, The concurrency constructs listed are all _blocking_ concurrency primitives, i.e. they put threads to sleep and wake them up. Since the goal of this work is pseudorandom execution of the application, trapping thread events is a central feature. The ability to mock the file system

Nothing we’re discussing constitutes a feature. We’re discussing stability enhancements, and important bug fixes. I think this disagreement is to some extent founded on our different premises about what a patch release should contain, and this seems to be the fault of incompletely specified
