Question 1

What's the difference between Census Sync and a webhook or API call?

Accepted Answer

Webhook = event-triggered one-way push (user signs up, fire email). Census Sync = bidirectional, SQL-powered, scheduled or real-time syncs. Census handles backfill (retroactive updates), transformations (dedupe, aggregate), and partial syncs. Webhook is simpler but requires custom code; Census is more powerful and requires no engineering.

Question 2

Can I sync deletes/updates or only inserts?

Accepted Answer

All three. Census Sync tracks row changes (UPSERTs, deletes). If a customer unsubscribes in Salesforce, Census can mark them as opted-out in your warehouse. Deletions are tricky though, most platforms don't support deleting records, only marking as inactive/archived.

Question 3

How long does a sync take from warehouse to CRM?

Accepted Answer

Real-time syncs trigger within 30-120 seconds of data warehouse refresh. Scheduled syncs run on intervals (hourly, daily, every 15min). CRM API rate limits (Salesforce = 15 calls/sec) can queue jobs. Bulk operations backfill faster than one-by-one. Typical: 10k records = 2-5 minutes.

Question 4

What if the downstream system (CRM) is down during sync?

Accepted Answer

Census retries with exponential backoff (3-5 retries over 1-2 hours). Failed batches are queued and can be manually retried. Partial syncs are rare; most syncs all-or-nothing. Build monitoring alerts so you know if a sync stalls for >30min.

Question 5

Can I sync from Postgres or only from data warehouses?

Accepted Answer

Both. Census works with operational DBs (Postgres, MySQL) and warehouses (Snowflake, BigQuery, Redshift). Postgres is lower-latency but needs SSL/VPN setup. Warehouse syncs are easier to audit (query source in SQL directly). Most companies use warehouse for audit/compliance.

Question 6

How do I debug if a sync failed for some rows?

Accepted Answer

Check Census > Logs > Failed Rows. Common issues: (1) duplicate key in destination (non-unique email in CRM), (2) required field missing from source SQL, (3) field mapping mismatch (expecting int, got string). Fix the query, resume from failure point. Census shows row-level errors, not just batch-level.

Question 7

What's the salary progression from analytics engineer to reverse-ETL specialist?

Accepted Answer

Analytics engineer ($90-130k) → Reverse-ETL/Activation engineer ($110-160k) → Data ops lead ($140-200k). The jump comes from owning end-to-end customer data activation (not just BI dashboards). Scarcest skill: SQL + workflow design + business intuition. Companies desperate for this post-Series A.
