Connectors

Cyntex inherits tapdata-connectors and provides 60+ official connectors, extensible via PDK (Plugin Development Kit).

Official Connectors (Partial List)

Category	Connectors
Relational databases	MySQL, PostgreSQL, Oracle, SQL Server, DB2
Document databases	MongoDB, Elasticsearch
Message queues	Kafka, RabbitMQ
Cloud databases	AWS RDS, Cloud SQL
SaaS	Salesforce, HubSpot
Files	S3, SFTP, local filesystem

PDK (Plugin Development Kit)

Connectors integrate via the PDK interface. Key mechanisms:

• API-level compatibility mechanism: Replaces pluginKit.properties; both sides’ versions are auto-derived; japicmp CI guards compatibility
• Idempotent registration: Content-hash deduplication; jars stored in MongoDB GridFS; engine distributes on demand
• Bundled catalog: Build-time full connector spec bundled into the CLI for offline use

Referencing Connectors in DSL

apiVersion: cyntex/v1
kind: source
id: mysql-prod
connector: mysql        # connector id (from catalog)
mode: cdc              # mode supported by the connector (capability matrix check)
config:
  host: db.internal
  port: 3306
  database: production

cyntex validate verifies that the connector × mode combination is valid (capability matrix layer). Invalid combinations produce an error — not silent failures.
