Event sourcing is an alternative technique of storing business data. Rather than updating a single database record, every change is captured in an immutable, append-only log. We never overwrite existing data. Instead, we create and store an event that represents what exactly has changed. From the business perspective. In order to recreate the current state of an entity we must go through all the events and reconstruct it from history. Event sourcing brings better auditing and debugging. Also, storing changes can be faster because it requires inserting a new record rather than updating an existing one.

Jest to odcinek podkastu:
Around IT in 256 seconds
Podcast for developers, testers, SREs... and their managers. I explain complex and convoluted technologies in a clear way, avoiding buzzwords and hype. Never longer than 4 minutes and 16 seconds. Because software development does not require hours of lectures, dev advocates' slide decks and hand waving. For those of you, who want to combat FOMO, while brushing your teeth. 256 seconds is plenty of time. If I can't explain something within this time frame, it's either too complex, or I don't understand it myself.
