DAS Cost-efficient Edition

DAS Cost-efficient Edition provides lightweight autonomy services. The database instances for which DAS Cost-efficient Edition is enabled are charged based on the subscription billing method. In addition to the features provided by DAS Basic Edition, DAS Cost-efficient Edition provides features such as automatic tablespace fragment recycling and performance insight.

DAS Enterprise Edition

DAS Professional Edition is renamed DAS Enterprise Edition. DAS Enterprise Edition has the following versions:

Each version supports the same features but has different billable items.

This allows flexible billing and reduces costs.

Data migration from DAS Enterprise Edition V1 or DAS Enterprise Edition V2 to DAS Enterprise Edition V3 is supported free of charge. Before the migration is complete, you are charged based on the source version. After the migration is complete, you are charged based on the destination version.

Billing

Impacts

• You can use the automatic tablespace fragment recycling feature without the need to enable DAS Enterprise Edition. This feature can be used after DAS Cost-efficient Edition is enabled.

• You can enable DAS Cost-efficient Edition or DAS Enterprise Edition to use the performance insight feature after the public preview ends.

  Important

  The public preview period of the performance insight feature ends on February 29, 2024. If you want to retain the data that is generated for the performance insight feature, you must enable DAS Cost-efficient Edition or DAS Enterprise Edition before the public preview ends. Otherwise, the performance insight feature is disabled and historical data is deleted after the public preview ends.

• The database instances for which DAS Enterprise Edition V1 or DAS Enterprise Edition V2 is enabled in the regions that support DAS Enterprise Edition V3 can be upgraded to DAS Enterprise Edition V3. Take note of the following items if you upgrade your database instance to DAS Enterprise Edition V3:

  • You are not charged storage fees for the data that is stored before you upgrade your database instance. If you perform operations such as querying, analyzing, or exporting data on the database instance, you are charged based on the billable items of DAS Enterprise Edition V3.

  • New data is billed based on billable items such as data ingestion, hot data storage, and cold data storage.

    Note

    DAS Enterprise Edition V3 uses a new billing method, which subdivides the billable items based on features. This allows flexible billing and reduces costs.
