Administración de recursos de Azure Cosmos DB for Apache Cassandra con plantillas de Azure Resource Manager
SE APLICA A: 
Cassandra
En este artículo, aprenderá a usar plantillas de Azure Resource Manager para ayudarle a implementar y administrar las cuentas, espacios de claves y tablas de Azure Cosmos DB.
Este artículo solo tiene ejemplos de cuentas de API para Cassandra; si quiere buscar ejemplos para otras cuentas de tipo de API, consulte los artículos sobre el uso de plantillas de Azure Resource Manager con la API de Azure Cosmos DB para NoSQL, Gremlin, MongoDB y Table.
Importante
- Los nombres de cuenta están limitados a 44 caracteres, todo en minúsculas.
- Para cambiar los valores de rendimiento, vuelva a implementar la plantilla con las RU/s actualizadas.
- Cuando agrega o elimina ubicaciones en una cuenta de Azure Cosmos DB, no puede modificar otras propiedades simultáneamente. Estas operaciones se deben realizar por separado.
Para crear cualquiera de los siguientes recursos de Azure Cosmos DB, copie la siguiente plantilla de ejemplo en un archivo JSON nuevo. También puede crear un archivo JSON de parámetros para usar al implementar varias instancias del mismo recurso con distintos nombres y valores. Hay muchas maneras de implementar plantillas de Azure Resource Manager, como, Azure Portal, la CLI de Azure, Azure PowerShell y GitHub.
Cuenta de Azure Cosmos DB para Cassandra con rendimiento aprovisionado de escalabilidad automática
Esta plantilla crea una cuenta de Azure Cosmos DB en dos regiones con opciones para la coherencia y la conmutación por error, con un espacio de claves y una tabla configurados para el rendimiento de escalabilidad automática. Esta plantilla también está disponible para implementar con un solo clic desde la galería de plantillas de inicio rápido de Azure.
