Price
ESTUARY

Open-Source, or predictably priced pipelines at $0.50 / GB plus $0.14 / hr (~$100/mo) for any capture or materialization.

Debezium

Open-Source. Typically requires 2+ full-time senior resources for production grade pipelines that require Kafka, Kafka Connect, Zookeeper, Debezium.

WHY IT MATTERS

Delivery
ESTUARY

Exactly-Once

WHY IT MATTERS

At-least once semantics can create duplicates the destination, creating inaccurate results and excess cost.

Scalability
ESTUARY

Estuary manages partitioning of tables and communicates with replication slot. This avoids DB memory problems that would otherwise put a limit on uptake.

Debezium

A connector handles 7K change events/second. Tables can be manually partitioned and multiple connectors created for more scalability.  Issues can happen when replication slots fill during backfills.

WHY IT MATTERS

For teams working with large tables, Debezium can be difficult to get working.

Schema Migrations
ESTUARY

Automated schema evolution

Debezium

Row-level data capture, but downstream destinations will have to be manually updated.

WHY IT MATTERS

Automation will ensure that your destination always matches your source.

Backfills
ESTUARY

Debezium

Manually triggered backfills to replay log from a point in time for a new consumer.

WHY IT MATTERS

Automation can save you time and money.

Transforms
ESTUARY

Streaming SQL and javascript transforms with joins on both real-time and historical data. DBT as a destination.
