Streaming with Change Data Capture into BigQuery

BigQuery, a component of the Google Cloud Platform, is a favored choice for businesses transitioning from batch processing to real-time streaming through Change Data Capture (CDC) due to its capabilities in real-time analytics, scalability, integration with other Google Cloud tools, and cost-effective pricing model. Streaming CDC involves capturing and transmitting altered data from sources like PostgreSQL and MongoDB to destinations like BigQuery, with open-source solutions such as Apache Kafka and Flink, or managed platforms like Streamkap, facilitating this process. Key considerations for streaming include the choice between inserts and upserts, handling schema drift, snapshotting, transformation methods, and managing large message sizes, all of which impact cost, performance, and data quality. Organizations must choose between open-source solutions, which offer customization but require significant maintenance, and managed services like Streamkap, which provide scalability, ease of use, and enterprise-level reliability. Effective monitoring and handling of schema drift are crucial for maintaining robust streaming pipelines, and Streamkap offers tools to simplify these processes, ensuring seamless schema evolution and efficient data flow management.
