Function buildColumnarIndexStreaming

buildColumnarIndexStreaming<TypeIDType>(source, parser, pool, onRecordIndexed?): StreamingColumnarIndexResult<TypeIDType>
Build the entity index by streaming, directly into typed-array columns (M7): identical parse and window behaviour to buildIndexStreaming, but completed records are encoded straight into a ColumnarIndexSink so the per-record object index never materialises. Peak JS heap for the index build becomes window + columns — the object phase (the dominant heap cost on large models) is gone.
Type Parameters
- TypeIDType extends number
Parameters
- source: ByteSource
  The byte source.
- parser: default<TypeIDType>
  The STEP parser (typed to the schema).
- pool: number
  Target window size in bytes.
- OptionalonRecordIndexed: ((localID: number, expressID: number, typeID: undefined | TypeIDType) => void)
  Optional per-record event (see buildIndexStreaming).
  - - (localID, expressID, typeID): void
    - Parameters
      localID: number
      expressID: number
      typeID: undefined | TypeIDType
      Returns void
Returns StreamingColumnarIndexResult<TypeIDType>
Columns, header, result, stats.
