| PostgreSQL (wal2json) | Yes | Yes | Logical replication with wal2json plugin |
| Neo4j | Yes | Yes | Timestamp-based tracking |
| JSONL Files | Yes | N/A | Batch import from JSON Lines |
| Apache Kafka | Yes | Yes | Consumer subscriptions with deduplication |

## Quick Start

```bash
# Install surreal-sync (Rust binary)
cargo install surreal-sync

# Full sync from PostgreSQL (trigger-based)
surreal-sync from postgres trigger-full \
  --connection-string "postgresql://user:pass@localhost/mydb" \
  --surreal-endpoint "http://localhost:8000" \
  --surreal-username root \
  --surreal-password root \
  --to-namespace prod \
  --to-database main

# Incremental CDC from PostgreSQL (wal2json)
surreal-sync from postgres wal2json \
  --connection-string "postgresql://user:pass@localhost/mydb" \
  --surreal-endpoint "http://localhost:8000" \
  --surreal-username root \
  --surreal-password root \
  --to-namespace prod \
  --to-database main

# Full sync from MongoDB
surreal-sync from mongo full \
  --connection-string "mongodb://localhost:27017/mydb" \
  --surreal-endpoint "http://localhost:8000" \
  --surreal-username root \
  --surreal-password root \
  --to-namespace prod \
  --to-database main

# Batch import from JSONL
surreal-sync from jsonl import \
  --file data.jsonl \
  --surreal-endpoint "http://localhost:8000" \
  --surreal-username root \
