So I'm missing something here, from what I gather so far, the methods that are being deprecated are to prevent a performance issue but the node structure that represents the jobs is in one place isn't it? How in the world are we getting a performance issue from that?
Is there a use case to demonstrate the performance problem? -- Jason On Tue, Jan 8, 2019, at 11:12 AM, Carsten Ziegeler wrote: > Hi, > > I agree, variant B sounds like the better option due to the reasons you > mention.
