Scaling through crisis: how infrastructure handled 1B messages in a single day
https://www.reddit.com/r/programming/comments/1nodab9/scaling_through_crisis_how_infrastructure_handled/

<!-- SC_OFF -->We recently published a piece on ShiftMag (a project by Infobip) that I think might interest folks here. It’s a candid breakdown of how Infobip’s infrastructure team scaled to handling 10 billion messages in a single day — not just the technical wins, but also the painful outages, bad regexes, and hard lessons learned along the way. <!-- SC_ON --> submitted by /u/shift_devs (https://www.reddit.com/user/shift_devs)

<!-- SC_OFF -->As you may know, this year Go switched its hashmap implementation from Buckets to Swiss tables looking for a boost in performance, how much? A lot according to Datadog (https://www.reddit.com/r/programming/comments/1m3di7x/how_go_124s_swiss_tables_saved_hundreds_of/): Go 1.24's Swiss Tables cut our map memory usage by up to 70% in high traffic workloads So I made a visual version of Swiss Tables and a tutorial so you can have an overall view of them and understand why they're so fast <!-- SC_ON --> submitted by /u/prox_sea (https://www.reddit.com/user/prox_sea)
