Hia! I’ve been asked to have a talk on Java in the near future. Right now I’m not quite sure what to talk about - it can br all things Java - Spring, Java9-11, Modules, architecutre and what not. Any suggestions on good topics I could cover?🔥

So, here we are using postgres in production with the fancy feature of UPSERT. We’ve got loads of request popping in, both new and updates - so the UPSERT getting triggered alot. Today we faced a problem with integer within our app stating that the number is too high. We were like «WTF? Already?!»! After looking in to the features of UPSERT, we came to realize that any sequence will be incremented regardless of an insert being handled. This results then in an ID field being defined with ids such as:
1
2
5
19
222
73377
282828282
Etc. You get the point..
This design is so WTF and I have absolutely no idea why anyone would like their IDs to be generated and incremended even though there is no insert. I hope it is due to my naivity that I cannot comprhend it. Oh well. UPSERT, you’re forever gone 👍🔥

Oracle Identity Manger. It just feels soooo unfinished and its just so damn tedious to work with! My god. Should've created the whole thing ourselves instead. The time we've used to fix shit.. #meh
