|  `streamThresholdBytes?` | `number` | `10 * 1024 * 1024` (10 MiB) | Byte-length threshold that switches between eager and streaming modes. **Remarks** - Below the threshold → eager (whole-file in memory). - At or above the threshold → streaming (line-offset index + per-line streaming reads). Set to `0` to force streaming mode; set to `Number.POSITIVE_INFINITY` to force eager mode. | [batteries/storage/flydrive/index.ts:59](https://github.com/NHTIO/ADK/blob/v1.20260605.0/src/batteries/storage/flydrive/index.ts#L59) |
