public class ColumnDefinitionVector extends ColumnDefinition
Represents a column definition for vector-based data. Extends ColumnDefinition to include properties and methods specific to vector data such as dimension, similarity metric, and vectorization service.

This class facilitates the configuration of vector columns in a data schema.

Example usage:

 
 ColumnDefinitionVector vectorColumn = new ColumnDefinitionVector()
      .dimension(128)
      .metric(SimilarityMetric.COSINE);

  • Constructor Details

    • ColumnDefinitionVector

      public ColumnDefinitionVector()
