I am just going by the outage post mortem report. I could not read the article after I read the first few lines - "feature file". I am stuck at consuming the design idea here where you allow multiple inserts for one feature [assuming you have some uniqueness constraint]. Even a simple key-value map per feature should have made the insertions as just a put/replace the value. I think that was not the case here, where cloudflare kept appending to the file for any feature to be added. And I am assuming the features are bot attack patterns as features. Anyway, there is something fundamental here cloudflare should rethink. If someone can educate me on the design, I can continue reading the next lines.
