Here’s the difference between debezium and Google BigQuery. The comparison is based on pricing, deployment, business model, and other important factors.
Debezium is an open source distributed platform for change data capture. Start it up, point it at databases, and apps can start responding to all of the inserts, updates, and deletes that other apps commit to databases. Debezium is durable and fast, so apps can respond quickly and never miss an event, even when things go wrong.
BigQuery is a fully-managed, serverless data warehouse that enables scalable analysis over petabytes of data. It is a Platform as a Service that supports querying using ANSI SQL. It also has built-in machine learning capabilities. BigQuery was announced in May 2010 and made generally available in November 2011.
