A mis-tagged funnel step corrupted last month's permit metrics. Raw logs still exist. What resilience action should the analyzer support?
Select an answer to reveal the explanation.
Short Explanation
Messed-up tags are fixable when you kept the raw tape. Correct the tracking, replay the logs, and rebuild the funnel like rewashing a load that used the wrong soap. Backfill is how analyzers recover instead of living with a bad month forever.
Full Explanation
Batch backfill and replay are resilience features for web analyzers when tracking bugs are found. Retaining raw logs in HDFS or a lake, or replaying from Kafka-oriented retention, enables corrected funnel metrics after tag fixes. Without replay capability, municipal reporting remains stuck with known-bad aggregates.
