Agree. I find “get started” usually is the best way to give an example of “entry point” to API. After that API documentation should get anyone covered for most of the cases. If API is big then it probably has primary and secondary set of features. Secondary then can be covered as tutorials.
How about SQL in PostgreSql?
query: select array_length(Array[]::text[], 1)
Output: null
Dont get me wrong JS is still awful
No it’s how Python wants you to format. Many times I want to separate two logical sections in one function and can’t coz Python go crazy
My colleague was working on migrating around dozens of batch jobs written in Java. All jobs had JPA/Hibernate but people which were writing those jobs didn’t understand abstraction and encapsulation. It end-up as vendor locked as you can imagine. Procedures, reading cursors, Oracle specific functions, metadata, logic spread between Java and PL/Sql, all the fun stuff, you know. So it took around one year of work to migrate to Postgres. And that’s with support of DBA who was helping with rewriting most complicated queries and procs. So yeah, don’t worry about that DBMS specific features.
Don’t get me wrong, though. Efforts spent on making design decisions should be proportional to potential size/complexity growth of the software. If you building todo list , how many different queries you might have in fairly pessimistic scenarios? Maybe couple dozens. Don’t bother with JPQL or HQL. If you expect your app to grow significantly. I’d do as much as possible to avoid my colleague’s fate.
I don’t think loop vs recursion choice is what significantly impacts performance in most cases. Most of the software I saw, suffer performance because of wrong API design or overall architecture. If app needs to fetch 100 objects from API which can provide only one object at the time no optimization will save that app.
App team - we need bulk API.
API team - cannot because of capacity, budget, backward compatibility, DB, 3rd patry API, not a KPI
Also it’s mostly QAs measuring performance and validating it with product guidelines which set by person who mostly detached from specific product and sometimes reality.
Please, can you give an example of such code snippets? I’m wondering what people consider reusable in different projects.
To me, generated code should not be committed at all. Again, I know nothing about this stack but code generators can have different behavior on different machines due to versions, flags and even OS. To deliver consistent results they should run in consistent env. It’s build time concern which CI/CD should take care of.
I didn’t get do you do integrations besides of your DB.
To me architecture sounds good anyway. I’m not GO dev but it looks like stack is your main problem not architecture itself. Multiple models is great long term approach which makes sure you are not leaking implementation details of your persistence/3rd party services to your client. You have layer of mappers where you can enrich model in optimal way and at the same time you can accommodate whatever client request/payload quirks you may need. Yes it’s sometimes annoying to add one field and pass it across all layers but it’s the price and software development is all about balance and compromises. I worked in projects that didn’t follow this architecture and any kind of change in DB/3rd party were cascading through entire application so end up changing hundreds of files instead of couple of models and few mappers
You may have issues with this architecture if you invoke services directly one from another for complex use cases. This can couple things together. If that’s what’s happening think if can apply Facade. Try using/reusing more trivial and focused services in Facade to make sure that for example Order service does not depend on Client service. Leave it to ClientOrderFacade.

Oh no kids can get to know how fucked up is this world. Maybe parents should’ve think about it when they were buying smartphone to 5 years olds
It’s Jython and it’s like 25 years old
But it doesn’t make sense. If I would have people which I like so much in the office would, you know, go to the office. If I don’t wonna go well… then I don’t like those people enough and there can’t be bonds anyway. We will just come, say hi, do job, go home. What a great creativity boost
First of all, what you are doing is integration via DB. Unless that was conscious, I would avoid using this approach. System is much easier to manage when DB/schema used at most by one app. You have two ways to achieve it, move towards micro-services or monolith. Yes monolith is still great for some use cases.
If we talking about your current system state every app should do changes in most backward compatible way. It worst cases it will lead to duplications. Let’s say if you want to change table X because there is such need for app A and at the same time app B uses this table. Instead of modifying X you create table Y that satisfies needs of A and make sure that data written into Y as well as into X to maintain B.

It’s called replica :)
Kinda, I guess we all can agree it’s more typical to deserialize into POJO where theres is no such thing as missing field. Otherwise why would you choose Java if you don’t use types. This great precondition for various stupid hacks to achieve „patching” resources, like blank strings or negative numbers for positive-only fields or even Optional as a field.
