From d1e7867020e334c771a102cda473577d96925ad0 Mon Sep 17 00:00:00 2001 From: Benoit Aubuchon Date: Fri, 6 Feb 2026 16:52:31 -0500 Subject: [PATCH 1/8] Split Wonderware pipeline into reusable connector + pipeline ## Changes ### New: Wonderware Connector (connector-registry/wonderware/) - Created 4-level hierarchy following SAP HANA CDC pattern - **config.py**: Connection configuration (host, port, database, credentials) - **connection_manager.py**: SQLAlchemy connection pool with circuit breaker - **reader.py**: Data extraction (discover_tags, fetch_history_data) - **connector.py**: High-level facade providing simple API - **models.py**: Domain models (TagInfo, HistoryRow, ConnectorStatus) - Complete test suite with mock fixtures ### Updated: Pipeline (pipeline-registry/wonderware_to_clickhouse/) - **wonderware_config.py**: Renamed to PipelineConfig, removed connection fields - Changed env prefix to WONDERWARE_PIPELINE_ - Kept only: tag_chunk_size, backfill_chunk_days, sync_schedule, etc. - **wonderware_sync.py**: Updated to use WonderwareConnector - **wonderware_backfill.py**: Updated to use WonderwareConnector - **app/wonderware**: Added symlink to connector (clean imports, no path manipulation) - **tests**: Updated to test PipelineConfig without connection fields ### Deleted - **wonderware_client.py**: Logic moved to connector ## Benefits - Connector can be reused by other pipelines - Clear separation: connector handles data access, pipeline handles ClickHouse - Follows established patterns (SAP HANA CDC) - Each component has independent tests Co-Authored-By: Claude Sonnet 4.5 --- connector-registry/wonderware/_meta/README.md | 34 +++ .../wonderware/_meta/connector.json | 9 + .../v1/514-labs/_meta/connector.json | 24 ++

If not provided, uses Windows Authentication (if available). + +```bash +export WONDERWARE_USERNAME=readonly_user +``` + +**Security Note**: For production, use a read-only user with minimal permissions (SELECT only on TagRef and History). + +#### WONDERWARE_PASSWORD (Optional) + +SQL Server password. Required if `WONDERWARE_USERNAME` is provided. + +```bash +export WONDERWARE_PASSWORD=secure_password +``` + +**Security Note**: Never commit passwords to version control. Use environment variables or a secrets manager. + +#### WONDERWARE_DRIVER (Optional) + +SQLAlchemy driver to use for SQL Server connection. Default: `mssql+pytds` + +```bash +export WONDERWARE_DRIVER=mssql+pytds # Default, pure Python driver +# or +export WONDERWARE_DRIVER=mssql+pyodbc # Requires ODBC driver +``` + +**Supported Drivers:** +- `mssql+pytds` - Pure Python driver (recommended, no dependencies) +- `mssql+pyodbc` - ODBC driver (requires SQL Server ODBC driver installed) +- `mssql+pymssql` - Alternative pure Python driver + +## Configuration Object + +You can also configure the connector programmatically using the `WonderwareConfig` class. + +### Basic Configuration + +```python +from wonderware import WonderwareConfig, WonderwareConnector + +# Create configuration object +config = WonderwareConfig( + host="wonderware-server.example.com", + port=1433, + database="Runtime", + username="readonly_user", + password="secure_password", + driver="mssql+pytds" +) + +# Build connector with config +connector = WonderwareConnector.build_from_config(config) +``` + +### Load from Environment + +```python +from wonderware import WonderwareConfig, WonderwareConnector + +# Load from environment with default prefix "WONDERWARE_" +config = WonderwareConfig.from_env() + +# Load from environment with custom prefix +config = WonderwareConfig.from_env(prefix="CUSTOM_") + +# Build connector +connector = WonderwareConnector.build_from_config(config) +``` + +### Connection String + +The connector generates SQLAlchemy connection strings automatically. You can inspect the generated string: + +```python +from wonderware import WonderwareConfig + +config = WonderwareConfig( + host="localhost", + port=1433, + database="Runtime", + username="user", + password="pass" +) + +print(config.get_connection_string()) +# Output: mssql+pytds://user:pass@localhost:1433/Runtime +``` + +## Advanced Configuration + +### Connection Pool Settings + +The connector uses SQLAlchemy's connection pooling. For advanced tuning, modify the `ConnectionPool` class: + +```python +from wonderware import WonderwareConfig, WonderwareConnector +from wonderware.connection_manager import ConnectionPool, CircuitBreaker + +config = WonderwareConfig.from_env() + +# Custom circuit breaker settings +circuit_breaker = CircuitBreaker( + failure_threshold=3, # Open after 3 failures (default: 5) + timeout_seconds=30 # Retry after 30 seconds (default: 60) +) + +# Create custom connection pool +pool = ConnectionPool(config, circuit_breaker=circuit_breaker) + +# Build connector with custom pool +connector = WonderwareConnector(config, connection_pool=pool) +``` + +### Retry Configuration + +The connector uses `tenacity` for automatic retry with exponential backoff. Default settings: +- **Max attempts**: 3 +- **Min wait**: 1 second +- **Max wait**: 10 seconds +- **Multiplier**: 1 (exponential backoff) + +These are configured in `connection_manager.py` and can be modified if needed. + +### Custom Driver Configuration + +#### Using ODBC Driver + +If you prefer ODBC: + +```bash +# Install pyodbc +pip install pyodbc + +# Configure environment +export WONDERWARE_DRIVER=mssql+pyodbc +export WONDERWARE_ODBC_DRIVER="ODBC Driver 17 for SQL Server" +``` + +Then modify the connection string generation to include the ODBC driver parameter. + +#### Using Windows Authentication + +For Windows Authentication (when running on Windows): + +```python +from wonderware import WonderwareConfig + +# No username/password - uses Windows auth +config = WonderwareConfig( + host="localhost", + port=1433, + database="Runtime", + driver="mssql+pyodbc" # ODBC supports Windows auth +) + +# Connection string: mssql+pyodbc://localhost:1433/Runtime +``` + +## Security Best Practices + +### 1. Use Read-Only Credentials + +Create a dedicated SQL Server user with minimal permissions: + +```sql +-- Create read-only user +CREATE LOGIN wonderware_readonly WITH PASSWORD = 'secure_password'; +USE Runtime; +CREATE USER wonderware_readonly FOR LOGIN wonderware_readonly; + +-- Grant SELECT only on required tables +GRANT SELECT ON TagRef TO wonderware_readonly; +GRANT SELECT ON History TO wonderware_readonly; +``` + +### 2. Store Credentials Securely + +Never hardcode credentials. Use one of these methods: + +**Environment Variables:** +```bash +export WONDERWARE_USERNAME=readonly_user +export WONDERWARE_PASSWORD=secure_password +``` + +**Secrets Manager (AWS):** +```python +import boto3 +import json +from wonderware import WonderwareConfig, WonderwareConnector + +def get_secret(secret_name): + client = boto3.client('secretsmanager') + response = client.get_secret_value(SecretId=secret_name) + return json.loads(response['SecretString']) + +secrets = get_secret('wonderware/credentials') +config = WonderwareConfig( + host=secrets['host'], + username=secrets['username'], + password=secrets['password'] +) +connector = WonderwareConnector.build_from_config(config) +``` + +**HashiCorp Vault:** +```python +import hvac +from wonderware import WonderwareConfig, WonderwareConnector + +client = hvac.Client(url='http://localhost:8200') +client.token = 'your-token' +secrets = client.secrets.kv.v2.read_secret_version(path='wonderware') + +config = WonderwareConfig( + host=secrets['data']['data']['host'], + username=secrets['data']['data']['username'], + password=secrets['data']['data']['password'] +) +connector = WonderwareConnector.build_from_config(config) +``` + +### 3. Use SSL/TLS Encryption + +For production deployments, enable encrypted connections: + +```python +from wonderware import WonderwareConfig + +config = WonderwareConfig( + host="wonderware-server.example.com", + port=1433, + database="Runtime", + username="user", + password="pass", + driver="mssql+pyodbc" +) + +# Add SSL parameters to connection string +# (Implementation depends on driver - modify connection_manager.py) +``` + +### 4. Network Security + +- Use firewalls to restrict SQL Server access +- Use VPNs or private networks for remote access +- Enable SQL Server authentication logging +- Monitor for unusual query patterns + +## Configuration Examples + +### Development Environment + +```bash +# .env.development +export WONDERWARE_HOST=localhost +export WONDERWARE_PORT=1433 +export WONDERWARE_DATABASE=Runtime +export WONDERWARE_USERNAME=dev_user +export WONDERWARE_PASSWORD=dev_password +export WONDERWARE_DRIVER=mssql+pytds +``` + +### Production Environment + +```bash +# .env.production +export WONDERWARE_HOST=wonderware-prod.internal.example.com +export WONDERWARE_PORT=1433 +export WONDERWARE_DATABASE=Runtime +export WONDERWARE_USERNAME=prod_readonly +# Password loaded from secrets manager +export WONDERWARE_DRIVER=mssql+pytds +``` + +### Testing Environment + +```python +# tests/conftest.py +import pytest +from wonderware import WonderwareConfig + +@pytest.fixture +def test_config(): + """Test configuration with mock database.""" + return WonderwareConfig( + host="localhost", + port=1433, + database="TestRuntime", + username="test_user", + password="test_password", + driver="mssql+pytds" + ) +``` + +## Troubleshooting Configuration + +### Connection Refused + +**Symptom**: Cannot connect to SQL Server + +**Solutions:** +1. Verify SQL Server is running: `telnet ` +2. Check firewall rules allow port 1433 +3. Verify SQL Server accepts remote connections +4.

Descriptions**: + +1. **discover_tags** + - Uses `connector.discover_tags()` to query TagRef table + - Returns list of active, non-system tags + - Example output: `["Temperature_01", "Pressure_02", "Flow_03", ...]` + +2. **chunk_date_ranges** + - Uses `PipelineConfig` for chunking parameters + - Splits time range into chunks (default: 1 day) + - Splits tags into groups (default: 10 tags) + - Example: 150 tags ร— 30 days = 450 work units (15 tag chunks ร— 30 date chunks) + +3. **fetch_and_insert** + - Fetches data using `connector.fetch_history_data()` + - Inserts to ClickHouse using `WonderwareBatchInserter.insert_rows()` + - Processes all combinations of tag chunks ร— date chunks + - Uses `inclusive_start=True` (BETWEEN operator) + +4. **finalize** + - Logs completion statistics (total rows, processed chunks, duration) + - No Redis state writes (ClickHouse is source of truth) + +**How to Trigger**: + +Via Temporal UI (http://localhost:8080): +```json +{ + "oldest_time": "2025-01-01 00:00:00" +} +``` + +Via Temporal CLI: +```bash +temporal workflow start \ + --task-queue wonderware_backfill \ + --type wonderware_backfill \ + --input '{"oldest_time": "2025-01-01
