3Frameworks

Framework

Are ingestion-layer failures causing the delay?

Is source API throttling or connector backpressure blocking ingestion?

Fivetran connector retry backlog: 4.2M rows pending (target: <200K)

Source API rate limit hit 3× in 24 hrs: 429 errors spiked to 18%

Has data volume growth outpaced ingestion capacity?

Event volume grew 3.8× in 90 days (new product launch)

Kafka consumer lag on orders topic: 4.7M events (normal: <50K)

Are transformation bottlenecks the primary cause?

Is Spark job skew causing excessive stage runtimes?

P99 Spark stage time: 4.2 hrs (SLA: 30 min) — 1 key holds 62% of data

Task straggler rate: 34% of tasks >5× median runtime

Are dbt model dependencies creating serial transformation chains?

7 of 12 critical models run sequentially (parallelizable)

Full refresh on 3 models re-scans 1.4TB daily — no incremental strategy

Are orchestration failures causing downstream lag?

Is Airflow task queue backlogged from cascading retries?

Active DAG queue: 847 tasks (baseline: 60) — 14× normal

3 upstream DAGs set to retry 5× each with no SLA-aware delay

Is SLA miss detection too slow to trigger escalation?

SLA alert fired 4.5 hrs after breach (monitoring interval: 1 hr)

No freshness checks on 8 of 12 critical tables (Great Expectations gaps)
