Class ScalingMode (1.19.0) 

ScalingMode(value)

The scaling mode for the reservation. This enum determines how the reservation scales up and down.

    Please note, in this mode, the ignore_idle_slots field must
    be set to true.
IDLE_SLOTS_ONLY (2):
    The reservation will scale up using only idle slots
    contributed by other reservations or from unassigned
    commitments. If no idle slots are available it will not
    scale up further. If the idle slots which it is using are
    reclaimed by the contributing reservation(s) it may be
    forced to scale down. The max idle slots the reservation can
    be max_slots - baseline capacity. For example, if max_slots
    is 1000, baseline is 200 and customer sets ScalingMode to
    IDLE_SLOTS_ONLY,

    1. if there are 1000 idle slots available in other
       reservations, the reservation will scale up to 1000 slots
       with 200 baseline and 800 idle slots.
    2. if there are 500 idle slots available in other
       reservations, the reservation will scale up to 700 slots
       with 200 baseline and 300 idle slots. Please note, in
       this mode, the reservation might not be able to scale up
       to max_slots.

    Please note, in this mode, the ignore_idle_slots field must
    be set to false.
ALL_SLOTS (3):
    The reservation will scale up using all slots available to
    it. It will use idle slots contributed by other reservations
    or from unassigned commitments first. If no idle slots are
    available it will scale up using autoscaling. For example,
    if max_slots is 1000, baseline is 200 and customer sets
    ScalingMode to ALL_SLOTS,

    1. if there are 800 idle slots available in other
       reservations, the reservation will scale up to 1000 slots
       with 200 baseline and 800 idle slots.
    2. if there are 500 idle slots available in other
       reservations, the reservation will scale up to 1000 slots
       with 200 baseline, 500 idle slots and 300 autoscaling
       slots.
    3. if there are no idle slots available in other
       reservations, it will scale up to 1000 slots with 200
       baseline and 800 autoscaling slots.

    Please note, in this mode, the ignore_idle_slots field must
    be set to false.

Enums
Name Description
SCALING_MODE_UNSPECIFIED Default value of ScalingMode.
AUTOSCALE_ONLY The reservation will scale up only using slots from autoscaling. It will not use any idle slots even if there may be some available. The upper limit that autoscaling can scale up to will be max_slots - baseline. For example, if max_slots is 1000, baseline is 200 and customer sets ScalingMode to AUTOSCALE_ONLY, then autoscalerg will scale up to 800 slots and no idle slots will be used.
