That UUID you chose? It might be killing your write speed.
Apps want randomness. Databases want order.

The conflict:
UUIDv4 ➝ Random inserts ➝ Index Fragmentation
UUIDv7 ➝ Sequential ➝ Fast B-Tree inserts

Tiny choice. Real impact at scale.

What is your default strategy?

@harshsingh1804 Exactly.Availability means nothing if the system is compromised or the data is wrong. Fail-safe > Fail-open for critical paths. Thanks Harsh!

“YouTube is availability-first” is a myth.

CAP is feature level.

YouTube: Video ➝ Availability Views ➝ Eventual Consistency Payouts ➝ Strong Consistency

Users forgive stale feeds, not wrong payouts.

Design isn't CP vs AP. It's context.

Thoughts? #SystemDesign #TechTwitter
