| `zeroMb` | `boolean` True if the processed data is 0 bytes. |
| `lessThanOneMb` | `boolean` True if the processed data is less than 1 MiB. |
| `processedMb` | `string (https://developers.google.com/discovery/v1/type-format format)` MiB data this query reads. Set if the data size is equal to or larger than 1 MiB. -1 means we could not fetch the processed bytes for this query. |
