Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 3876, "days_push": 7, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Debezium is an open source distributed platform for change data capture (CDC) that streams row-level database changes as events, most commonly via Apache Kafka Connect source connectors. It uses log-based CDC to capture inserts, updates, and deletes with low latency, durable offset tracking, and a unified change event model across many databases.

## Use cases
- stream database changes to kafka in real time
- keep elasticsearch search index in sync with a database
- invalidate caches when rows change
- implement the transactional outbox pattern for microservices
- replicate data from mysql or postgres to a data warehouse
- capture deletes and old row state without triggers or last-updated columns
- build event-driven services that react to data changes

## When to choose
- you need reliable, ordered, low-latency change data capture from a supported database
- you already run or can deploy Apache Kafka / Kafka Connect
- you want to avoid polling, dual writes, or database triggers
- you need durable event history so consumers can go down and resume without missing events

## When to avoid
- you have no Kafka or event-streaming infrastructure and only need simple one-off ETL jobs
- your database is not among the supported connectors
- you only need batch data sync on a schedule rather than streaming changes
- you cannot grant the replication/log-reading privileges Debezium requires on the source database
