1 / 5
Fill in: 'We ___ a Lambda trigger on the DynamoDB stream, rather than polling the table on a schedule nobody actually needs.'
We 'attach a trigger' — the standard, simple collocation for wiring a stream to a consumer. The other options are less idiomatic here.
2 / 5
Fill in: 'A short stream retention window can ___ a lagging consumer missing records that already expired.'
We say a short window will 'leave' a lagging consumer missing records — the standard, natural collocation for the resulting data loss. The other options aren't idiomatic here.
3 / 5
Fill in: 'We ___ the stream view type explicitly as NEW_AND_OLD_IMAGES, rather than a default that omits data the consumer actually needs.'
We 'set a view type' — the standard, simple collocation for configuring what the stream captures. The other options are less idiomatic here.
4 / 5
Fill in: 'We ___ every batch of stream records for idempotency before processing, rather than double-applying an event nobody's actually deduped.'
We 'check a batch' — the standard, simple collocation for verifying idempotency before processing. The other options are less idiomatic here.
5 / 5
Fill in: 'We ___ consumer iterator age continuously, rather than discovering a stalled Lambda only once records have actually expired.'
We 'track age' — the standard, simple collocation for monitoring how far behind a stream consumer is. The other options aren't idiomatic here.
