Ingestion

Ingestion

Ingestion is the first step in Outrun's data synchronization process. After adding a source, Outrun begins collecting and storing raw data from your systems using the most appropriate method for each source type.

Ingestion Methods

Outrun uses two primary methods for data ingestion, automatically selecting the best approach for each source:

Real-Time Streams

When a source supports real-time data streams, Outrun leverages these for immediate data collection:

• Instant Collection: Data is ingested as soon as it's available
• Event-Driven: Triggered by actual data changes in the source system
• Continuous Flow: Maintains persistent connection for ongoing data flow
• Examples: Salesforce PubSub, webhook-enabled systems

Batch Jobs

For sources without real-time capabilities, Outrun runs periodic batch jobs:

• Scheduled Collection: Jobs run at configured intervals
• Comprehensive Sweep: Aims to import all available data
• Configurable Timing: Frequency depends on your settings and source capabilities
• Incremental Updates: Only collects changed data after initial sync

Stream Storage Architecture

All ingested data is stored in dedicated stream collections that preserve the original format while adding essential metadata.

Stream Collection Naming

[sourceId]_stream

Each source gets its own dedicated stream collection:

• hubspot_abc123_stream - HubSpot source data
• salesforce_def456_stream - Salesforce source data
• zoho_ghi789_stream - Zoho CRM source data

Data Storage Principles

First-In, First-Out (FIFO)

• Chronological Order: Data stored in the order it was received
• Temporal Integrity: Maintains timeline of data changes
• Audit Trail: Complete history of all data ingestion
• Processing Order: Ensures consistent processing sequence

Original Format Preservation

• Minimal Transformation: Data stored as close to API response format as possible
• Native Structure: Preserves source system's data structure and relationships
• Field Names: Original field names and data types maintained
• Nested Objects: Complex object structures preserved intact

Metadata Enrichment

Outrun appends system metadata without altering source data:

{
  // Original source data (unchanged)
  "id": "12345",
  "email": "john@example.com",
  "firstName": "John",
  "lastName": "Doe",
  
  // Outrun metadata (appended)
  "_outrun": {
    "sourceId": "hubspot_abc123",
    "sourceType": "hubspot",
    "ingestedAt": "2024-01-15T10:30:00Z",
    "apiEndpoint": "/contacts/v1/contact/12345",
    "processed": false,
    "processingAttempts": 0,
    "lastModified": "2024-01-15T09:45:00Z"
  }
}

Metadata Fields

Outrun adds comprehensive metadata to track data lineage and processing:

Source Information

• sourceId: Unique identifier for the source instance
• sourceType: Type of source system (hubspot, salesforce, etc.)
• apiEndpoint: Specific API endpoint used for data collection
• objectType: Native object type from source system

Timing Information

• ingestedAt: When Outrun received the data
• lastModified: When the data was last modified in source system
• syncJobId: Identifier for the sync job that collected this data
• batchId: Batch identifier for grouped operations

Processing Status

• processed: Whether data has been processed into standardized objects
• processingAttempts: Number of processing attempts
• processingErrors: Any errors encountered during processing
• consolidatedAt: When data was moved to consolidation stage

Data Quality

• dataQuality: Quality score and validation results
• duplicateOf: Reference to original record if duplicate detected
• validationErrors: Field-level validation issues
• enrichmentStatus: Status of any data enrichment processes

Value-Added Services

The metadata-enriched stream data enables powerful value-added services:

Data Lineage Tracking

• Complete History: Track data from source to destination
• Change Attribution: Identify what caused data changes
• Impact Analysis: Understand downstream effects of changes
• Compliance Auditing: Meet regulatory audit requirements

Data Quality Monitoring

• Quality Metrics: Track data quality scores over time
• Validation Reporting: Identify common data quality issues
• Trend Analysis: Monitor data quality improvements
• Alert Systems: Notify of significant quality degradation

Performance Analytics

• Ingestion Rates: Monitor data collection performance
• Processing Times: Track how long data takes to process
• Error Rates: Identify and resolve ingestion issues
• Capacity Planning: Plan for scaling data operations

Advanced Processing

• Machine Learning: Use historical data for predictive analytics
• Data Enrichment: Enhance data with external sources
• Anomaly Detection: Identify unusual data patterns
• Custom Transformations: Apply business-specific data rules

Ingestion Configuration

Batch Job Settings

Configure how often batch jobs run based on your needs:

• Polling Interval: How frequently to check for new data
• Backfill Period: How far back to collect historical data
• Rate Limiting: Respect source system API limits
• Error Handling: Retry logic and failure recovery

Real-Time Stream Settings

Configure real-time data collection parameters:

• Event Filtering: Which events to capture
• Buffer Settings: How to handle high-volume streams
• Failover Logic: Fallback to batch jobs if stream fails
• Monitoring: Health checks and performance metrics

Best Practices

Initial Setup

1. Start Small: Begin with recent data to test ingestion
2. Monitor Performance: Watch for rate limit issues
3. Validate Data: Ensure data quality meets expectations
4. Gradual Expansion: Increase scope after successful testing

Ongoing Management

1. Regular Monitoring: Check ingestion health and performance
2. Error Review: Address ingestion errors promptly
3. Capacity Planning: Monitor storage and processing needs
4. Performance Optimization: Adjust settings based on usage patterns

Data Quality

1. Source Validation: Ensure source data quality before ingestion
2. Metadata Review: Use metadata for data quality insights
3. Error Analysis: Investigate and resolve recurring issues
4. Continuous Improvement: Refine ingestion based on learnings

Next Steps

Ingestion is the foundation of reliable data synchronization. Understanding this process helps you optimize your data collection strategy.
