# Funciones beta y características experimentales

> ClickHouse tiene funciones beta y características experimentales. Esta página de documentación explica su definición.

Como ClickHouse es de código abierto, recibe muchas contribuciones no solo de empleados de ClickHouse, sino también de la comunidad. Estas contribuciones suelen desarrollarse a ritmos distintos; algunas funcionalidades pueden requerir una larga fase de prototipado o más tiempo para recibir suficientes comentarios de la comunidad e iterar antes de considerarse de disponibilidad general (GA).

Dado que no siempre está claro cuándo una funcionalidad pasa a considerarse de disponibilidad general, las distinguimos en tres categorías: **Beta**, **Experimental** y **Vista previa privada**.

Las **funciones beta** cuentan con soporte oficial del equipo de ClickHouse. Las **características experimentales** son prototipos tempranos impulsados por el equipo de ClickHouse o por la comunidad y no cuentan con soporte oficial. Las funcionalidades en **vista previa privada** avanzan por un camino claro hacia la disponibilidad general, pero aún tienen una aplicabilidad limitada y no se recomiendan para uso en producción.

Las secciones siguientes describen explícitamente las características de las funcionalidades **Beta**, **Experimental** y en **vista previa privada**:

<h2 id="beta-features">
  Funciones Beta
</h2>

* En desarrollo activo para que sean de disponibilidad general (GA)
* Los principales problemas conocidos pueden seguirse en GitHub
* La funcionalidad puede cambiar en el futuro
* Pueden estar habilitadas en ClickHouse Cloud
* El equipo de ClickHouse ofrece soporte para las funciones beta

A continuación encontrarás las funciones consideradas Beta en ClickHouse Cloud y disponibles para su uso en tus servicios de ClickHouse Cloud.

Nota: asegúrate de usar una versión actual de la configuración de [compatibilidad](/es/reference/settings/session-settings/compatibility#compatibility) de ClickHouse para poder utilizar una función incorporada recientemente.

<h2 id="experimental-features">
  Características experimentales
</h2>

* Puede que nunca lleguen a ser GA
* Pueden eliminarse
* Pueden introducir cambios importantes que rompan la compatibilidad
* Su funcionalidad puede cambiar
* Deben habilitarse explícitamente
* El equipo de ClickHouse **no ofrece soporte** para las características experimentales
* Pueden carecer de funcionalidades importantes y de documentación
* No pueden habilitarse en ClickHouse Cloud

Tenga en cuenta: no se permite habilitar características experimentales adicionales en ClickHouse Cloud aparte de las que se indican arriba como Beta.

<h2 id="private-preview-features">
  Características en vista previa privada
</h2>

* Con una hoja de ruta clara hacia la disponibilidad general (GA)
* Su aplicabilidad todavía es limitada
* No se recomiendan para uso en producción
* Su funcionalidad puede cambiar en el futuro
* Deben habilitarse explícitamente
