Surreal-Sync -- Data Migration and Synchronization

Surreal-Sync is a CLI tool for migrating data from various database sources to SurrealDB with full and incremental synchronization via Change Data Capture (CDC).

Supported Sources

Source	Full Sync	Incremental CDC	Method
MongoDB	Yes	Yes	Change streams
MySQL	Yes	Yes	Trigger-based CDC + sequence checkpoints
PostgreSQL (triggers)	Yes	Yes	Trigger-based CDC + sequence checkpoints
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

# 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 \
  --surreal-password root \
  --to-namespace prod \
  --to-database main

# Consume from Kafka
surreal-sync from kafka consume \
  --bootstrap-servers "localhost:9092" \
  --topic my-events \
  --surreal-endpoint "http://localhost:8000" \
  --surreal-username root \
  --surreal-password root \
  --to-namespace prod \
  --to-database main

CLI Pattern

surreal-sync from <SOURCE> <COMMAND> \
  --connection-string [CONNECTION STRING] \
  --surreal-endpoint [SURREAL ENDPOINT] \
  --surreal-username [SURREAL USERNAME] \
  --surreal-password [SURREAL PASSWORD] \
  --to-namespace <NS> \
  --to-database <DB>

Key Features

Automatic schema inference and SurrealDB table creation
