Re: [DISCUSS] Depth First Repeat step
I presume that would be some source of technical derailment to this approach Not necessarily, just the “step to define traversal order” idea. The RepeatStep, at least from what I’ve seen, seems simplest to implement as a BFS. BFS is easily made depth first with a stack. I think that can still be the case with the RepeatStep here, it would just need another means of determining which algorithm to use. That could probably be “Does this repeat traversal end with a barrier step?” If that seems reasonable for RepeatSteps then maybe that could help with some of Pieter’s “check for a negative” concerns. Full BFS: manually add barrier()‘s Mixed mode: Default, let strategies do their thing OR remove strategies and manually add your own barrier() Full DFS: execute .withoutStrategies(Lazy...) This sounds reasonable, but my main concern is there’s not really any great documentation around what LazyBarrierStrategy really does. Sure, you can read the code, but I think that as the documentation currently sits, inserts barrier()-steps into a traversal where appropriate in order to gain the "bulking optimization." is a bit vague. “Where appropriate” should probably be well defined in the documentation so users can have a good understanding of when that is without having to go to the code.

ApacheCon North America 2018 schedule is now live.
Dear Apache Enthusiast, We are pleased to announce our schedule for ApacheCon North America 2018. ApacheCon will be held September 23-27 at the Montreal Marriott Chateau Champlain in Montreal, Canada. Registration is open! The early bird rate of $575 lasts until July 21, at which time it goes up to $800. And the room block at the Marriott ($225 CAD per night, including wifi) closes on August 24th. We will be featuring more than 100 sessions on Apache projects. The schedule is now online at https://apachecon.com/acna18/ The schedule includes full tracks of content from Cloudstack[1], Tomcat[2], and our GeoSpatial community[3]. We will have 4 keynote speakers, two of whom are Apache members, and two from the wider community. On Tuesday, Apache member and former board member Cliff Schmidt will be speaking about how Amplio uses technology to educate and improve the quality of life of people living in very difficult parts of the world[4]. And Apache Fineract VP Myrle Krantz will speak about how Open Source banking is helping the global fight against poverty[5]. Then, on Wednesday, we’ll hear from Bridget Kromhout, Principal Cloud Developer Advocate from Microsoft, about the really hard problem in software - the people[6]. And Euan McLeod, VP VIPER at Comcast will show us the many ways that Apache software delivers your favorite shows to your living room[7]. ApacheCon will also feature old favorites like the Lightning Talks, the Hackathon (running the duration of the event), PGP key signing, and lots of hallway-track time to get to know your project community better. Follow us on Twitter, @ApacheCon, and join the disc...@apachecon.com mailing list (send email to discuss-subscr...@apachecon.com) to stay up to date with developments. And if your company wants to sponsor this event, get in touch at h...@apachecon.com for opportunities that are still available. See you in Montreal!
