This is quite timely as we're just gearing up to begin pushing the work we've been doing on CEP-21 into the public domain.
This CEP is a slightly different from others that have gone before in that it touches almost every area of the system. This presents a few implementation challenges, most obviously around feature flagging and incremental merging. When we began prototyping and working on the design presented in CEP-21 it quickly became apparent that doing things incrementally would push an already large changeset into gargantuan proportions. Keeping changes isolated and abstracted would itself have required a vast amount of refactoring and rework of existing code and tests. I'll go into more detail in a CEP-21 specific mail shortly, but the plan we were hoping to follow was to work in a long lived topic branch, with JIRAs, sensible commit history and CI, and defer merging to trunk until the work as a whole is useable and meets all the existing bars for quality, review and the like. > On 3 Feb 2023, at 12:43, Josh McKenzie <jmcken...@apache.org> wrote: > > Anything we either a) have to do (JDK support) or b) have all agreed up front > we think we should do (CEP).
