Module profile_builder 

Shared conversion from StreamingColumnCollection / StreamingStatistics into ColumnProfile and quality-check sample maps.

All engines that need to produce a ColumnProfile should call build_column_profile instead of constructing one manually. This ensures consistent stats calculation and pattern detection.

Structs

ColumnProfileInput

Inputs that every engine can provide for centralized profile construction.

TextLengths

Pre-computed text length stats from streaming/columnar engines.

Functions

build_column_profile

Build a ColumnProfile from engine-agnostic inputs.

infer_data_type_streaming

Infer DataType from StreamingStatistics sample values.

profile_from_stats

Convert a single column’s StreamingStatistics into a ColumnProfile.

profile_from_stats_with_hints

Convert a single column into a ColumnProfile while applying semantic hints.

profiles_from_streaming

Convert all columns in a StreamingColumnCollection into ColumnProfiles.

profiles_from_streaming_with_hints

Convert all columns into ColumnProfiles while applying semantic hints.

quality_check_samples

Build a sample HashMap from a StreamingColumnCollection suitable for QualityMetrics::calculate_from_data().
