1. 1 Durable Objects: state nhất quán theo object (chat room, booking). SQLite-backed class khi cần query local. Durable Objects: strongly consistent per-object state (chat room, booking). SQLite-backed class when you need local queries. Durable Objects៖ state consistent ខ្លាំងតាម object (chat room, booking)។ Class SQLite-backed ពេលអ្នកត្រូវការ query ក្នុងមូលដ្ឋាន។

2. 2 Queues: việc nền, fan-out, retry — không làm HTTP request dài trong Worker. Queues: background work, fan-out, retries — do not hold a long HTTP request in the Worker. Queues៖ ការងារផ្ទៃក្រោយ, fan-out, retries — កុំរក្សា HTTP request វែងក្នុង Worker។

3. 3 Workflows: bước dài, durable, sleep/retry có mô hình — onboard/order pipeline. Workflows: long steps, durable, modeled sleep/retry — onboard/order pipelines. Workflows៖ ជំហានវែង, durable, sleep/retry មានគំរូ — onboard/order pipelines។

4. 4 Hyperdrive: Postgres/MySQL query nhanh từ Worker (connection pooling). Cần DB public hoặc path VPC. Hyperdrive: faster Postgres/MySQL from a Worker (connection pooling). Needs a public DB or a VPC path. Hyperdrive៖ Postgres/MySQL លឿនជាងពី Worker (connection pooling)។ ត្រូវការ DB សាធារណៈ ឬ path VPC។

   Checkpoint: Checkpoint: Checkpoint៖ Bạn chọn đúng một để lab tuần này. Ba cái kia ghi “sau”. You pick exactly one to lab this week. The other three are written down as “later”. អ្នកជ្រើសរើសតែមួយដើម្បី lab សប្តាហ៍នេះ។ បីទៀតសរសេរទុកថា “later”។

Cẩn thận Watch out ប្រុងប្រយ័ត្ន

• Hyperdrive không thay D1 — đó là bridge tới database bên ngoài. Hyperdrive does not replace D1 — it is a bridge to an external database. Hyperdrive មិនជំនួស D1 — វាគឺជា bridge ទៅ database ខាងក្រៅ។
