SDK example
import { S3TablesClient, CreateTableBucketCommand } from "@aws-sdk/client-s3tables";
const s3t = new S3TablesClient({
region: "us-east-1",
endpoint: "http://127.0.0.1:4727",
credentials: { accessKeyId: "parlel", secretAccessKey: "parlel" },
});
const { arn } = await s3t.send(new CreateTableBucketCommand({ name: "lake" }));
Access via MCP / preview URL
Reachable through the parlel pool MCP bridge and preview URL. No auth setup required.
Surface coverage
This emulator faithfully replicates the API surface most application code and agents exercise. Anything below the supported lines is either an intentional design choice for a fast, zero-cost local emulator (✓ By design) or a candidate for a future release (⟳ Roadmap) — never a silent inaccuracy.
Legend: ✅ fully supported · ◐ accepted (stored, not strictly enforced) · ✓ by design · ⟳ on the roadmap.
| Area | Limitation |
|---|---|
| Iceberg | Table metadata is recorded; no actual Iceberg files written. |
| Data | No row-level read/write; control-plane catalog only. |
| Maintenance | Compaction/snapshot management is not modeled. |
| Policies | Bucket/table policies are not enforced. |
Configuration — test.env
Copy these into your test.env (used by the bridge sidecar flow). Tokens are Parlel's seeded test credentials — any non-empty value is accepted by the emulator, so you rarely need to change them. Swap in real credentials only when pointing at the live service in prod.env.
