Special Guest: Edgar Pino In this episode of Elixir Mix, the panel talks with https://github.com/edgar971?tab=followers who talks with the panel about the latest version of Ecto! They discuss Ecto’s new features and how easy of a transition it was to go from the previous to the newest version. https://github.com/edgar971?tab=followers is a software engineer who currently resides in Utah! Check out today’s episode! Show Topics: 0:00 – https://devchat.tv/get-a-coder-job/ 1:04 – Mark: Hello! Please give us your background? 1:16 – Guest: I have been in https://elixir-lang.org for the past year or two and I have been living in Utah. 1:48 – Mark: I love the nature and state parks. Winter is coming, so I hope you are ready! 1:58 – Guest: Winter...hopefully it will be great! 2:20 – Panelists and guest go back-and-forth. 2:30 – Mark: Let’s talk about your blog posts about Ecto. What are your new announcements? 2:52 – Guest: Our new version was released a few weeks ago. 3:32 – Panel. 3:38 – The guest talks about the old and new versions of Ecto. 4:03 – Panel: What is new and how is this going to affect me (the new version)? 4:11 – Panel: The transition was pretty painless for me. The only change was the breaking-up of the adapter ad also the timestamp bit. That was it. 4:34 – Panel: Yeah that micro-timestamp surprised me for a second, but it wasn’t that bad after all. 4:52 – Guest: Yeah it was painless for me, too. 5:19 – Panel: Edgar can you talk about the change and what they did with the timestamps? 5:32 – The guest answers the question. 5:54 – Panel: Elm opted to use the micro-millisecond, too. Time zones aren’t a thing. 6:24 – Mark. 7:08 – Panel: My tests are the only reason why I care about the millisecond. 7:21 – Mark: With the upgrade don’t do what I did. Mark talks about how he updated and the issues he had. 8:47 – Guest: Pattern matching? 8:53 – Mark: Yep that sort of stuff. I didn’t need to do it and it was a learning experience. Edgar, please give us an introduction to the blog posts? Why did you want to document it? 9:18 – Guest: I always used Ecto with Phoenix but started learning Ecto by itself. I jotted down notes that I thought was interesting. That’s how it started. 10:17 – Mark: See links in the show notes. Using a gen to use the repo – this is one thing that I didn’t know was an option. 10:46 – Guest. 11:01 – Mark asks a question. 11:10 – Guest: Not really PHP applications but listening to web messages and hot topics but you are doing the database and serving data... 11:40 – Guest talks about Ecto and the different versions and features. 12:09 – Mark chimes-in. 12:23 – Panel: Yep – it’s under the hood and it’s for business logic and doesn’t have a web piece. Stop writing tings for the web – it’s a fad. 12:50 – Mark: It’s an umbrella and saw this through the Phoenix generators. 13:54 – Guest talks about web applications. 14:06 – Mark: Let’s talk about schema and databases? 14:23 – Panelist chimes-in. 14:51 – Panelists and guest talk about schemas, apps, and more. Check it out here. 16:13 – Guest: You will get the data and pass it in as a structure and... 16:23 – Mark: Here is a map of what I’d like you to do on my behalf. It goes to a chain set and I will turn it into a string and this is why it’s failed. 17:25 – Panel. 17:31 – Mark: It’s not hard and it’s pretty easy. Let’s talk about blog posts. 18:10 – Panel. 18:22 – Mark: I use https://github.com/absinthe-graphql/absinthe in the library in Elixir to support https://graphql.org 18:50 – Panel. 19:06 – Guest: The total number of results and only once did I need a more complicated thing. 19:34 – Mark: I haven’t had a need for those. 20:01 – Panelists and guests talk about the hypothetical situations where and how they would use certain features for said situations. 20:23 – Guest: You don’t have to understand right out-of-the-box. 20:40 – Panel: Have you used stored functions as meta-columns in an https://hexdocs.pm/ecto/Ecto.html schema? 20:48 – Panelist explains. 21:24 – Guest: I have used them in the past and now I don’t. For me it was hard to debug – maybe it’s just me. 21:43 – Panel: I was introduced to them through a colleague of mine. 21:53 – Mark chimes-in and talks about him being a DOT NET developer. 22:18 – Panelist chime-in, too! 22:50 – Mark. 23:16 – Panel: It was an awful time and not a good idea. 70 pages! Debugging it was hard. 23:35 – Mark: That experience was apart of that burn that I had before. I wanted to stay far away from it as far as I could. 24:00 – Panel: When I was doing it in DOT NET we didn’t have migrations. 24:12 – Panelist continues. 24:32 – Guest: I wonder if... 24:37 – Panel: It’s just a sequel – it’s not just an https://hexdocs.pm/ecto/Ecto.html specific feature. 24:48 – Guest. 24:53 – https://www.freshbooks.com 26:01 – Mark: Edgar you were interested also in HOW Ecto was built. What experience did you have? 26:21 – Guest answers the question. 28:22 – Panel: No you typed REPO there. 28:30 – Guest: Whenever you save or make an update it’s a method. Unlike Ecto you have to all it something else. 28:47 – Panel: Hey let me get those article posted and someone did it in Loop and that is a lot of queries. 29:03 – Guest: Yeah that’s a good point. 29:45 – Mark: Something I’ve noticed is that they talk about performance improvements and better memory usage. Go read about it- it’s great. They talk about HOW Ecto is working and what is behind the scenes. 31:15 – Mark: Another feature that I have seen is UPSERTS. 31:50 – Guest talks about UPSERTS, too. 32:34 – Mark: Say I have a system that has 3 servers and it’s rolling updates (it will take down one and put up the new code, etc. and it will cycle) one thing they added was a lock on the migration table. I don’t know if you’ve had this – once it hits production data it is slow. Mark continues. 33:20 – Panel: I think it was just luck of the draw. 33:30 – Mark continues. 33:57 – The guest talks about his experience with the above-mentioned scenario. 34:20 – Mark: I like that you both have had goo experiences with your upgrades. I want people to be excited and know that there are great features out there. 34:49 – Guest: Yes, I have found that the blog post is helpful. It’s good to get adapted to the new changes. 35:17 – Panel: Yeah I normally don’t have teasers up to the actual upgrade. 35:28 – Panel: The community is nice and people made a good effort to communicate and help people. They did a GOOD job of helping people to feel comfortable within the transition from one version to the next! 41:37 – https://www.lootcrate.com END – https://www.cachefly.com Links:
