Parameters
Name Description
data array

Optional. Data for populating the Message object.

↳ period Google\Protobuf\Duration

Time that clients should wait before adjusting the target rate again. If clients adjust rate too frequently, the impact of the previous adjustment may not have been taken into account and may over-throttle or under-throttle. If clients adjust rate too slowly, they will not be responsive to load changes on server side, and may over-throttle or under-throttle.

↳ factor float

If it has been at least one period since the last load adjustment, the client should multiply the current load by this value to get the new target load. For example, if the current load is 100 and factor is 0.8, the new target load should be 80. After adjusting, the client should ignore factor until another period has passed. The client can measure its load using any unit that's comparable over time For example, QPS can be used as long as each request involves a similar amount of work.
