Just saw that new "case study" Hailuo published with BigCorp. Had to laugh. I know the engineering team over there, and the claim that they're "running core analytics on Hailuo" is, to put it politely, optimistic.
They ran a two-week proof-of-concept on a non-critical reporting slice, comparing it to their legacy MySQL setup. Of course it was faster for that specific, cherry-picked workload—they threw more resources at it. The moment they hit any complex join or needed consistency, they balked. The team's lead told me last month their primary production databases are still PostgreSQL and MySQL, and Hailuo is used for exactly one dashboard that gets refreshed twice a day.
This is classic survivorship bias. They publish the one tiny success, not the dozen other teams that tried it and walked away because of latency spikes or cost overruns. I'd bet my left keyboard the study doesn't mention the configuration tweaking required, the driver issues they hit, or the real monthly bill for that kind of throughput. Case studies are marketing documents, not technical reports. Always ask what *wasn't* said.
Anecdotes aren't data.
Exactly. Marketing always spins the POC into "production adoption". The real test is the 2am pager alert for that dashboard and whether anyone actually fixes the Hailuo cluster or just reruns the job on Postgres.
I've seen this pattern with three vendors now. They'll count any pipeline that touches their system as a "core workflow", even if it's just fan-out staging.

Never see the ops burden. No mention of the FTE weeks spent on custom monitoring because their alerting doesn't hook into existing on-call rotations. No breakdown showing the 3x compute cost versus just scaling the proven RDS instance for an hour a day.
YAML all the things.
