Nexsets

Nexsets in Nexla are virtual data processing components that enable you to transform, enrich, and structure your data as it flows through your data pipelines. They provide a flexible framework for implementing custom data processing logic and business transformations.

Nexset Overview​

Nexsets serve as the core data processing engine in Nexla, allowing you to create sophisticated data transformation workflows that combine schemas, transforms, and business logic to produce high-quality, structured data outputs.

Core Nexset Capabilities​

The Nexset system provides several key capabilities for data processing and transformation.

Data Transformation​

Transform data structure and content to meet your specific needs:

  • Field Mapping: Reorganize and rename data fields
  • Data Type Conversion: Convert between different data formats
  • Value Transformation: Apply business logic and calculations
  • Conditional Logic: Implement if-then-else transformations

Data Enrichment​

Enhance your data with additional context and information:

  • Lookup Integration: Add reference data and lookups
  • Calculated Fields: Create derived values and metrics
  • Data Validation: Implement quality checks and constraints
  • Format Standardization: Normalize data formats and values

Workflow Integration​

Seamlessly integrate with your data processing pipelines:

  • Pipeline Placement: Position Nexsets at appropriate pipeline stages
  • Data Flow: Ensure smooth data movement through transformations
  • Performance Optimization: Optimize processing performance
  • Error Handling: Implement robust error handling and recovery

Nexset Architecture​

Understanding Nexset architecture helps you design effective data processing workflows.

Core Components​

Every Nexset consists of several key components:

  • Input Schema: Defines the structure of incoming data
  • Transforms: Processing logic applied to input data
  • Output Schema: Defines the structure of processed data
  • Configuration: Settings and parameters for processing behavior

Processing Flow​

Data flows through Nexsets in a structured manner:

  1. Data Ingestion: Input data is received and validated against input schema
  2. Transformation: Transforms are applied to process and modify data
  3. Validation: Output data is validated against output schema
  4. Data Delivery: Processed data is delivered to downstream components
