Il 15 settembre 2026, tutti gli ambienti Cloud Composer 1 e Cloud Composer 2 versione 2.0.x raggiungeranno la fine del ciclo di vita pianificata e non potrai più utilizzarli. Ti consigliamo di pianificare la migrazione a Cloud Composer 3.
Cloud Composer 1 ha ambienti che eseguono un numero costante di worker.
Quando crei un ambiente, specifichi il numero di nodi. Questo numero corrisponde al numero di worker nel tuo ambiente. Cloud Composer distribuisce il carico tra tutti i worker dell'ambiente. Oltre a eseguire i worker Airflow, i nodi dell'ambiente eseguono anche gli scheduler e altri componenti dell'ambiente.
Puoi scalare l'ambiente modificando il numero di nodi.
Parametri di scalabilità e rendimento
Puoi controllare i parametri di scalabilità e prestazioni del tuo ambiente modificando i tipi di macchine utilizzati dai componenti del database e del server web di Airflow del tuo ambiente. In questo modo puoi scalare l'ambiente verticalmente, oltre alla scalabilità orizzontale fornita dall'impostazione del numero di nodi. Puoi modificare i tipi di macchine del database e del server web Airflow in qualsiasi momento.
Imposti il tipo di macchina per i nodi dell'ambiente quando crei un ambiente.
Non puoi modificare questo parametro in un secondo momento. Ciò significa che non puoi scalare i worker Airflow verticalmente in Cloud Composer 1.
Più pianificatori
Airflow 2 può utilizzare più di uno scheduler Airflow contemporaneamente. Questa funzionalità di Airflow è nota anche come HA scheduler. In Cloud Composer 1,
puoi impostare il numero di pianificatori per il tuo ambiente e modificarlo in qualsiasi
momento. Cloud Composer non scala automaticamente il numero di pianificatori nel tuo ambiente.

This number\ncorresponds to the number of workers in your environment. Cloud Composer distributes load between all workers in your\nenvironment. In addition to running Airflow workers, your environment nodes\nalso run schedulers and other environment components.\n\nYou can scale your environment by changing the number of nodes in your\nenvironment.\n\nScale and performance parameters\n\nYou can control the scale and performance parameters of your environment by\nadjusting the machine types used by the Airflow database and web server\ncomponents of your environment. By doing so you can scale your environment\nvertically, in addition to the horizontal scaling provided by the number of\nnodes setting. You can adjust machine types of the Airflow database and web\nserver at any time.\n\nYou set the machine type for environment nodes when you create an environment.\nYou cannot change this parameter later. It means that you cannot scale Airflow\nworkers vertically in Cloud Composer 1.\n\nMultiple schedulers\n\nAirflow 2 can use more than one Airflow scheduler at the same time. This\nAirflow feature is also known as the **HA scheduler**. In Cloud Composer 1,\nyou can set the number of schedulers for your environment and adjust it at any\ntime. Cloud Composer does not automatically scale the number of\nschedulers in your environment.\n\nFor more information about configuring the number of schedulers for your\nenvironment, see [Scale environments](/composer/docs/composer-1/scale-environments#scheduler).\n\nDatabase disk space\n\nDisk space for the Airflow database automatically increases to accommodate the\ndemand.\n\nWhat's next\n\n- [Scale environments](/composer/docs/composer-1/scale-environments)\n- [Cloud Composer pricing](/composer/pricing)\n- [Create environments](/composer/docs/composer-1/create-environments)\n- [Environment architecture](/composer/docs/composer-1/environment-architecture)"]]
