Overview

The auto scaling policy that scales a table based on the ratio of consumed to provisioned capacity.

Instance Attribute Details

#disable_scale_in ⇒ Boolean

Specifies if ‘scale-in` is enabled.

When auto scaling automatically decreases capacity for a table, the table *scales in*. When scaling policies are set, they can’t scale in the table lower than its minimum capacity.

Returns:

  • (Boolean)

#scale_in_cooldown ⇒ Integer

Specifies a ‘scale-in` cool down period.

A cooldown period in seconds between scaling activities that lets the table stabilize before another scaling activity starts.

Returns:

  • (Integer)

#scale_out_cooldown ⇒ Integer

Specifies a scale out cool down period.

A cooldown period in seconds between scaling activities that lets the table stabilize before another scaling activity starts.

end

#target_value ⇒ Float

Specifies the target value for the target tracking auto scaling policy.

Amazon Keyspaces auto scaling scales up capacity automatically when traffic exceeds this target utilization rate, and then back down when it falls below the target. This ensures that the ratio of consumed capacity to provisioned capacity stays at or near this value. You define ‘targetValue` as a percentage. A `double` between 20 and 90.

Returns:

  • (Float)
