Important

OSS bills you for the full provisioned capacity, not the amount of data prefetched into the cache. For example, if you provision 100 GB and prefetch 50 GB, you are billed for 100 GB.

Billing example

Scenario: You provision 100 GB of accelerator capacity and use it for 24 hours.

Accelerator fee = Provisioned capacity × Usage duration × Price per GB
               = 100 GB × 24 hours × <price-per-GB>

Replace <price-per-GB> with the rate for your region. See OSS Pricing.
