Function buildColumnarIndexStreamingAsync

buildColumnarIndexStreamingAsync<TypeIDType>(source, parser, pool, onRecordIndexed?, onProgress?, yieldIntervalMs?): Promise<StreamingColumnarIndexResult<TypeIDType>>
Cooperative twin of buildColumnarIndexStreaming: identical columnar build, but the parse periodically yields to the event loop (see buildIndexStreamingAsync) and reports absolute byte-cursor progress — the browser-facing variant for large models.
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
- OptionalonProgress: ((absoluteByteCursor: number) => void)
  Optional absolute byte-cursor progress callback.
  - - (absoluteByteCursor): void
    - Parameters
      absoluteByteCursor: number
      Returns void
- OptionalyieldIntervalMs: number
  Minimum ms between event-loop yields.
Returns Promise<StreamingColumnarIndexResult<TypeIDType>>
Columns, header, result, stats.
