# Meta parameters

Intelie Live supports a set of meta parameters that can change the behavior of any Pipes query.

All the meta parameters listed below can be used in three different ways:

* `#property=value` on the span of a query
* `.property:value` on the filter of a query
* `=> @meta value as property` on the body of a query

{% hint style="info" %}
Some meta parameters can also change the behavior of some [frontend features](/data-visualization/pipes-modifiers-on-standard-charts.md). Those parameters can only be used with the `@meta` pipe.

| `storage`                                                                                                                                                     | boolean            |         |
| Forces a real time query to run entirely from the storage.                                                                                                    |                    |         |

| Allows spans that reference events in future. This implies the query will run entirely on storage (using simulated real time, when necessary).                |                    |         |
| `disableLatestOptimization`                                                                                                                                   | boolean            |         |

| Force query to stay alive after history load even if not required. This attribute has precedence over `disableRealtime`.                                      |                    |         |

| Valid only on datasource reset: it determines whether the reset procedure. It should truncate the whole collection before starting the procedure.             |                    |         |
