Fast, lightweight access to Apache Arrow data.

/**
 * Decode [Apache Arrow IPC data][1] and return parsed schema, record batch,
 * and dictionary batch definitions. The input binary data may be either
 * an `ArrayBuffer` or `Uint8Array`. For Arrow data in the IPC 'stream' format,
 * an array of `Uint8Array` instances is also supported.
 *
 * This method stops short of generating views over field buffers. Use the
 * `createData()` method on the result to enable column data access.

 * @param {ArrayBufferLike | Uint8Array | Uint8Array[]} data

 *  array may contain one or more self-contained messages. Messages may NOT
