Debezium

DE//AGENT currently lists 2 resources under Debezium: 1 skill, 1 project. Everything below is derived from the live registry — counts, capabilities, verification state and security posture come from the curated records, never from marketing copy.

Documented learning objectives across these resources:

• Order change events deterministically — via CDC Merge Designer
• Handle deletes (tombstones) without losing history — via CDC Merge Designer
• Make the merge idempotent under replay — via CDC Merge Designer
• Configure a logical replication slot safely — via Postgres → CDC → Kafka → Lakehouse
• Order events by LSN and dedupe before merging — via Postgres → CDC → Kafka → Lakehouse
• Handle tombstones without losing history — via Postgres → CDC → Kafka → Lakehouse

These resources map to stage: Streaming (2). Follow the four-phase roadmap to place this topic inside a progression instead of learning it in isolation.

Every entry, its shape and its trust state — sorted by the registry's composite score. This table is the honest version of a marketing comparison: no sponsored placements, no unverifiable claims.

How scores are computed: source quality score.

Highest composite score first:

1. CDC Merge Designer score 39.5 — advanced
2. Postgres → CDC → Kafka → Lakehouse score 33.65 — advanced

Scores rank provenance, completeness and trust — read how verification works before adopting anything.

Reach for these with production experience: CDC Merge Designer, Postgres → CDC → Kafka → Lakehouse.

Security-flagged entries: CDC Merge Designer (1 flag), Postgres → CDC → Kafka → Lakehouse (4 flags). Flags mean the record declares capabilities like credential use or write access — read the security posture on each page before connecting.

• CDC Merge Designer — Produces a MERGE (or Delta/Iceberg merge) that applies inserts, updates and deletes from a CDC stream correctly, including out-of-order events and tombstones. details
• Postgres → CDC → Kafka → Lakehouse — Capture changes from Postgres with Debezium, stream through Kafka, and merge into a lakehouse table with correct ordering, deletes and replay safety. details

Real install commands from the registry — read the source before running any of them:
