SHARED WRITES DON'T SCALE

pic related. It's not "a little bit of scalability"; it is "no scalability".

watch and achieve webscale, or be damned.

>Read and Write Considered Harmful

Dijkstra-meme titles considered reddit-tier fucking cancer. Right up there with "[...] 2: Electric Boogaloo"

my first thought, but the video's too good to hold that against him

▶Anonymous 10/02/18 (Tue) 22:15:59 No.981585

No shit, did you expect some magic to make a bottleneck not be a problem?

Niklaus Wirth came up with that title, not Dijkstra. The paper was Dijkstra's but it was Wirth who published and provactively renamed his paper, as Wirth is a somewhat extreme anti-goto ideologue.

Dijkstra's original title was "A Case Against the Goto Statement", by the way.

I will have to finish the video later, but he brings up a lot of good points so far. This is why I'm generally lean towards event sourcing architectures, where the DB is a materialized view, because it separates out the reads from the writes.

The ideas behind event sourced systems:

Greg Young has a funny video introducing the concept more concretely:
