Change Data Capture (CDC)

# Best Change Data Capture (CDC) Tools in 2026

Change data capture reads a database’s transaction log and streams every insert, update and delete to somewhere else as it happens: a warehouse, a search index, a cache or another service. It replaces nightly dumps and polling queries that hammer production. Here are the main CDC tools in 2026, from an Apache-licensed engine you run yourself to managed pipelines billed by volume.
