Kumo

By operation

Every operation this target implements, with how much of it diverges and how much of it it covers, on the same two axes as the figures above. The counts are fails over the operation's whole size. ✓ full, ◑ partial, ✗ failing, – unsupported. The emulator directory lists support across targets.

Where it falls short

Operations Kumo implements and answers differently from real DynamoDB, biggest gap first. This is what its divergence figure counts. Open one for the exact tests, or see the conformance suite.

What it doesn't attempt

Operations Kumo declines rather than gets wrong, so none of this counts towards its divergence. It is what the gap in its 78.3% coverage is made of. Each test here skipped itself because the target's own feature probe said the operation isn't implemented, which is often a deliberate choice rather than a defect.
