Description

Billing method

Compute nodes

  • Compute nodes contain primary and read-only nodes.

  • You are charged for compute nodes based on their region, specifications, and usage duration.

  • Pay-as-you-go

  • Subscription

  • Serverless

Note

Storage space

  • Storage space is used to store cluster data files, index files, log files, and temporary files. Log files include online and archived logs. You are charged for the amount of storage space that you use.

  • The storage space amount for which you are charged depends on the volume of stored data and the period of time for which the data is retained.

  • Pay-as-you-go + storage plan

  • Pay-as-you-go

  • Subscription

  • Serverless

Note

For more information about the billing rules for storage, see Overview.

Backup storage space (only charged after the free quota is reached)

  • Backup files consume storage space. PolarDB provides a free storage quota for backup files. If the actual storage capacity that you use exceeds the quota, you are charged for the excess storage capacity consumed by backup files.

  • The backup storage amount for which you are charged depends on the size of data backup files and the period of time for which the files are retained.

  • Pay-as-you-go + storage plan

  • Pay-as-you-go

  • Serverless

Note

The subscription billing method is not supported for backup storage space. If you select Subscription when you purchase a cluster, the subscription billing method is applied only to compute nodes, and you may still be charged for other items, such as the storage of backup files. We recommend that you purchase storage plans to offset fees generated by level-1 backups. For more information, see Billing rules of backup storage that exceeds the free quota.

SQL Explorer (optional)

  • The SQL Explorer feature on Database Autonomy Service (DAS) provides value-added capabilities such as security audits and performance diagnostics. After you enable this feature, you are charged for the amount of storage space consumed by audit logs. A free storage quota is provided for the SQL Explorer feature. After this quota is exhausted, you are charged for the amount of excess storage space.

  • The storage space amount for which you are charged depends on the size of audit logs and the period of time for which the logs are retained.

  • Pay-as-you-go

  • Serverless

Note
  • The SQL Explorer feature does not support the subscription billing method. If you select Subscription when you purchase a cluster, the subscription billing method is applied only to compute nodes, and you may still be charged for other items, such as the audit logs generated by the SQL Explorer feature.

  • For more information about the billing rules of SQL Explorer, see Billing rules of SQL Explorer (optional).

Note
  • The global database network (GDN) feature is provided free of charge. You are charged only for each PolarDB cluster that uses the GDN feature. For more information, see Overview.

  • The multi-zone deployment feature is provided free of charge. For more information, see Multi-zone deployment.
