Slow Sync Issue between Sentry and BigQuery

Summary

User reports a performance issue with slow data sync from Sentry to BigQuery, specifically observing rapid extraction of events but prolonged loading times, with logs showing repeated entries. Seeking advice on potential causes and resolutions.


Question

Hello,

I am having trouble with a very slow sync between Sentry and BigQuery

The sync extracts events records from Sentry very quickly, but seems to take a very long time loading them to the destination. In previous syncs, it took ~8 hours to load ~1000 records.

I am using
Incremental | Append + Deduped
for the sync mode

Looking at the logs, the same log entries keep appearing a couple of times every minute.

Any advice on the cause and possible fix for this would be much appreciated.
