Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).


The fair share policy for a scheduling policy.



A value used to reserve some of the available maximum vCPU for fair share identifiers that aren't already used.

The reserved ratio is (computeReservation/100)^ActiveFairShares where ActiveFairShares is the number of active fair share identifiers.

For example, a computeReservation value of 50 indicates that Amazon Batch reserves 50% of the maximum available vCPU if there's only one fair share identifier. It reserves 25% if there are two fair share identifiers. It reserves 12.5% if there are three fair share identifiers. A computeReservation value of 25 indicates that Amazon Batch should reserve 25% of the maximum available vCPU if there's only one fair share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three fair share identifiers.

The minimum value is 0 and the maximum value is 99.

Type: Integer

Required: No


The amount of time (in seconds) to use to calculate a fair share percentage for each fair share identifier in use. A value of zero (0) indicates that only current usage is measured. The decay allows for more recently run jobs to have more weight than jobs that ran earlier. The maximum supported value is 604800 (1 week).

Type: Integer

Required: No


An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0.

Type: Array of ShareAttributes objects

Required: No
