What to check before you buy
Decide your latency needs. Batch ELT suits daily analytics; CDC and streaming suit operational use cases. The architecture should match the question.
Check connector coverage for your specific sources and their update cadence. Verify schema-change handling: the best platforms adapt automatically. Confirm deployment options for your security requirements. Finally, model total cost including compute: consumption pricing behaves very differently across vendors.
Batch vs streaming: an honest decision framework
The industry markets streaming as the future and batch as legacy. The reality is that most companies need both, and choosing wrong in either direction wastes money. Here is how to decide per use case.
Choose batch when the decision cadence is daily or slower. Financial reporting, marketing attribution, executive dashboards and most ML training run fine on data that is hours old. Batch pipelines are simpler, cheaper and easier to debug. A well-run hourly or daily ELT setup handles the majority of analytics workloads, and there is no prize for making a monthly report real-time.
Choose streaming when latency has business value. Fraud detection, inventory availability, personalization, operational alerting and live dashboards justify the complexity. The test is concrete: what decision changes if the data is one minute old instead of one hour old? If you cannot name it, you do not need streaming.
Choose change data capture when the source is a database and freshness matters. CDC reads the database transaction log instead of polling tables, which gives near-real-time updates without hammering the source system. It is the right pattern for operational syncs: keeping the warehouse, search index and cache consistent with the production database.
Beware the complexity tax. Streaming systems introduce exactly-once semantics, late-arriving data, schema evolution and state management. These are solvable problems, but they require skills most analytics teams do not have yet. A streaming pipeline nobody on the team fully understands is a 3 a.m. pager incident waiting to happen.
The pragmatic architecture for most companies: batch ELT as the backbone, CDC-based streaming for the handful of use cases where latency pays, and a platform that handles both so the team learns one system. Start with batch, add streaming where the business case is explicit, and revisit the mix annually.
How we chose
We selected data integration platforms with live products and real data-team customers, spanning managed, open-source and real-time architectures, using vendor sites, documentation and public reviews. Pricing is consumption or quote-based, so all prices are See website. We did not run pipelines.
The hidden costs of data pipelines
Pipeline pricing pages show the visible costs. The hidden ones decide whether the project stays within budget.
Compute creep is the biggest. Consumption-based pricing means every inefficient query, every unnecessary full refresh and every duplicated pipeline costs real money. Teams routinely discover that a single misconfigured sync burns more than the rest of the account combined. Set up cost alerts per pipeline from day one, and review the top spenders monthly. The cheapest platform with no cost visibility often ends up more expensive than a pricier one with good metering.
Schema change firefighting is the hidden labor cost. Sources change their APIs and schemas constantly; each change can break downstream models and dashboards. Platforms that handle schema evolution automatically save real engineering hours. When evaluating, ask specifically: what happens when a source adds a column, renames a field or changes a type? The answer reveals how much babysitting you are buying.
Backfill and reprocessing costs surprise everyone once. When a bug corrupts three months of data, replaying history through the pipeline can cost as much as months of normal operation. Understand the platform's backfill pricing and mechanics before you need them at 2 a.m.
Data quality debt compounds silently. Pipelines that move data faithfully but never validate it deliver dashboards nobody trusts. Budget for testing and monitoring: freshness checks, volume anomalies, schema tests and row-count reconciliations. The platform may include these or you may build them; either way, they are part of the cost.
Finally, the exit cost. Migrating hundreds of pipelines to another platform is a project measured in quarters. This is not an argument against buying; it is an argument for choosing carefully, negotiating contract terms that protect you, and keeping pipeline definitions portable where the platform allows it.
Frequently asked questions
What is the difference between ETL and ELT?
ETL transforms data before loading; ELT loads raw data into the warehouse first, then transforms it there. Modern cloud platforms favor ELT for flexibility and compute economics.
What is CDC?
Change Data Capture: streaming database changes in real time instead of batch extracts. Estuary and Debezium-based tools specialize in it.
Fivetran vs Airbyte: which should I choose?
Fivetran for fully managed reliability with minimal engineering. Airbyte for open-source control, custom connectors and avoiding vendor lock-in.
Where does dbt fit?
dbt handles transformation inside the warehouse. It complements ingestion tools like Fivetran or Airbyte rather than replacing them.
What is a data lakehouse?
Architecture combining data lake storage economics with warehouse query performance, popularized by Databricks. Integration tools increasingly target lakehouse destinations.
Do I need real-time data integration?
Only if use cases demand it: operational dashboards, fraud detection, personalization. Daily reporting works fine on batch ELT at lower cost.
Should a small team build pipelines with open source or buy managed?
Buy managed unless data engineering is a core competency you plan to keep. Open-source tools save license fees but cost engineering time in setup, monitoring and maintenance, which is usually the scarcer resource. The breakeven point sits around having at least one dedicated data engineer; below that, managed platforms are cheaper in practice.
How do I estimate data integration costs?
Model three components: platform fees (often consumption-based on rows synced or compute used), implementation effort, and ongoing maintenance. The biggest variable is usually data volume growth, so project costs at two to three times current volume. Ask vendors for a cost estimate based on your actual source list and sync frequencies, not list prices.
What skills does a data team need to run modern pipelines?
SQL is the foundation, plus enough Python for custom logic, and familiarity with the warehouse you run on. Streaming adds event-driven concepts and operational skills like monitoring and incident response. The scarcest skill is usually data modeling: designing tables and transformations that stay correct as sources evolve. Hire or train for that first.
