Is Airbyte actually better than Fivetran or just cheaper?

Airbyte is cheaper (free if you self-host), but that's not why you should use it. The real advantage is [open-source](https://github.com/airbytehq/airbyte) - when connectors break (and they will), you can fix them yourself instead of waiting for support tickets. Fivetran's great if you want managed service and don't mind paying $1000+/month. Use Airbyte if you need control or have budget constraints.

How often does stuff actually break?

Runs solid in production. When things do break, it's usually: - Source APIs changing without warning (looking at you, Facebook Marketing API) - Network dying during 500GB syncs because of course it does - Schema changes that make destination tables shit themselves - Containers running out of memory because someone forgot to set limits - Memory leaks from Java connectors that nobody wants to debug - Rate limiting hell when APIs decide you're 'suspicious' The [AI Copilot](https://airbyte.com/blog/diagnose-data-pipeline-sync-errors-with-ai) catches the obvious stuff. For everything else, check logs then ask in [Slack](https://airbyte.com/community). Lost an entire weekend debugging MySQL binlog replication - turns out you need `gtid-mode=ON` on the replica. The docs mentioned it in paragraph 47 of some random setup guide.

What's the real setup time like?

Docker deployment: 10 minutes if you've done this before, 3 hours if you're Googling 'what is a container' while following the tutorial. Cloud: 5 minutes to sign up, 45 minutes figuring out why your first connector won't authenticate (probably OAuth scope issues). Kubernetes: Block out your entire weekend unless you dream in YAML. The [getting started docs](https://docs.airbyte.com/using-airbyte/getting-started/) don't suck, which is refreshing.

Can I really build custom connectors that fast?

If it's a simple REST API that actually follows standards, sure. Built one for our CRM in 25 minutes, but that's because their API wasn't completely fucked. Reality check: APIs with creative pagination, OAuth flows designed by sadists, or response formats that make you question humanity will eat your entire afternoon. The GraphQL support helps, but you're still screwed if the API returns XML inside JSON strings.

How much will it actually cost me?

- **Open Source**: Free (but you pay for server costs and your time) - **Cloud**: Starts free, then $0.10-$0.30 per million rows typically - **Enterprise**: $48k+/year for big deployments Hidden costs that'll bite you: server infrastructure (EC2 isn't free), monitoring tools, and paying someone to get paged at 3am when syncs explode. Cloud eliminates most of this headache. Learned this the hard way - runaway sync racked up a $3,200 AWS bill in one weekend when a connector got stuck in a retry loop. Set resource limits BEFORE you go to production, not after.

Does CDC actually work without destroying everything?

[PostgreSQL CDC](https://airbyte.com/solutions/database-replication) works well - uses logical replication so it won't murder your primary database. MySQL binlog parsing is solid too. Gotchas that'll ruin your day: - PostgreSQL 9.x is basically unsupported (upgrade already) - Need `REPLICA IDENTITY FULL` or updates/deletes won't sync properly - Initial sync of 500GB tables takes about as long as you'd expect

Is the community real help or just marketing theater?

[Slack community](https://airbyte.com/community) (25k+ people) is genuinely useful. Posted about a PostgreSQL SSL handshake issue at 2am, got three different solutions by morning coffee. Real engineers, not chatbots. GitHub issues get responses from people who actually write code. Open source means you're talking to developers, not tier-1 support reading from scripts.

What happens when the free version stops cutting it?

You'll hit walls around: - 50+ connectors running simultaneously - Multi-TB daily syncs (your AWS bill will hate you) - Compliance team demanding SOC 2 reports and audit logs Migration to Cloud doesn't suck - same interface, same connector configs. Enterprise adds the enterprise-y stuff like SSO, audit trails, and someone to yell at when things break.

Function: ELT (Extract, Load, Transform) data integration platform that moves data from sources to destinations.

Architecture: Open-source with managed cloud and enterprise options. Uses ELT approach - raw data loaded first, transformed using warehouse compute power.

Configuration That Works in Production

Deployment Options

Open Source: Free, self-hosted, full control
Cloud: Managed service, $0.10-$0.30 per million rows
Enterprise: $48k+/year, SOC 2 compliance, audit logs

Critical Production Settings

PostgreSQL CDC: Requires REPLICA IDENTITY FULL or updates/deletes fail
MySQL binlog: Needs gtid-mode=ON on replica
BigQuery: Must use --enable_standard_sql=true or legacy SQL errors occur
Container limits: Required to prevent memory leaks from Java connectors
Connection pools: Monitor PostgreSQL connection pool exhaustion

Resource Requirements

Time Investment

Docker deployment: 10 minutes (experienced) to 3 hours (learning)
Cloud setup: 5 minutes signup + 45 minutes OAuth debugging
Kubernetes: Full weekend unless YAML expert
Custom connector: 20-45 minutes (simple REST API)

Infrastructure Costs

Hidden costs: Server infrastructure, monitoring, 3am support engineer
Runaway sync risk: Can rack up $3,200+ AWS bills in one weekend if retry loops occur
Initial sync: 500GB tables take expected time, plan accordingly

Expertise Requirements

Basic: Docker, API authentication concepts
Advanced: YAML for Kubernetes, CDC configuration, connector debugging
Custom connectors: REST/GraphQL API understanding, OAuth flows

Critical Warnings

Production Failure Modes

Source API changes: Facebook Marketing API changes without warning
Network failures: During large (500GB+) syncs
Schema changes: Break destination tables
Memory issues: Java connector memory leaks
Rate limiting: APIs flag usage as suspicious
Authentication: OAuth scope issues most common

Breaking Points

UI limitation: Breaks at 1000 spans, making large distributed transaction debugging impossible
Connector limits: 50+ simultaneous connectors stress free version
Sync frequency: Sub-5 minute syncs require Enterprise ($48k+/year)
Memory leaks: Long-running syncs crash after 6 hours (fixed in v1.0.0+)

Database-Specific Issues

PostgreSQL 9.x: Essentially unsupported, upgrade required
