CData Sync vs Debezium

CData Sync replicates data from databases, SaaS applications and APIs to databases, data lakes and data warehouses. CData says it supports over 250 sources and offers a catalog of cloud and on-premises destinations. Pipelines can use incremental loading and, for supported sources, real-time Change Data Capture. ETL and ELT transformations are available through SQL or dbt Core and Cloud. Users can schedule pipelines and receive email, Slack or Teams notifications when workflows finish or fail. Sync can run on premises, in cloud environments or through CData-hosted Sync Cloud, and is listed for Linux, Windows, web, API and self-hosted use. Its APIs and scripting can manage connections and jobs, inspect status and history, download logs, and run custom behavior around jobs. It can adjust destination schemas when source schemas change; its overview says it does not delete destination columns or reduce their size. CData documents TLS/SSL encryption and encrypted sensitive configuration values and reports third-party SOC 2 Type II and ISO/IEC 27001:2022 audits. A 14-day trial is available; there is no free plan.

Debezium captures row-level database changes and delivers them to applications as events, so they can respond to inserts, updates, and deletes. Its connectors use database logs for low-delay capture without requiring changes to the data model, and can take initial or incremental snapshots, filter schemas, tables, and columns, and mask selected values. Listed databases include MongoDB, MariaDB, MySQL, PostgreSQL, SQL Server, Oracle, Db2, and Cassandra. Connectors for Vitess, Spanner, Informix, CockroachDB, YashanDB, Ingres, and Milvus are marked incubating and may change without backward compatibility. A common deployment uses Apache Kafka Connect; Debezium can also run through Debezium Server or as a library in JVM applications. Debezium Server can send serialized events to Amazon Kinesis, Google Cloud Pub/Sub, and Apache Pulsar. Ready-to-use transformations support routing, filtering, and event flattening. Debezium is free under the Apache Software License 2.0. Its quay.io container images are for testing and evaluation, not production.
