所有已实现的接口:

RateLimitingStrategy

@PublicEvolving
public class CongestionControlRateLimitingStrategy
extends Object
implements RateLimitingStrategy

A RateLimitingStrategy implementation that does the following:

• Scales up when any request is successful.
• Scales down when any message in a request is unsuccessful.
• Uses a scaling strategy to scale up/down depending on whether the request is successful.

This strategy works well for throughput-limited record-based sinks (e.g. Kinesis, Kafka).

方法详细资料

registerInFlightRequest

public void registerInFlightRequest(RequestInfo requestInfo)

从接口复制的说明: RateLimitingStrategy

Registers the information of requests being sent (e.g. to track the current inFlightMessages / requests).

指定者:

registerInFlightRequest 在接口中 RateLimitingStrategy

参数:

requestInfo - Data class containing information on request being sent

registerCompletedRequest

public void registerCompletedRequest(ResultInfo resultInfo)

从接口复制的说明: RateLimitingStrategy

Registers the result of completed requests (e.g. to track the current inFlightMessages / requests). Any dynamic scaling on failed messages should be done here.

指定者:

registerCompletedRequest 在接口中 RateLimitingStrategy

参数:

resultInfo - Data class containing information on request completed

shouldBlock

public boolean shouldBlock(RequestInfo requestInfo)

从接口复制的说明: RateLimitingStrategy

Decides whether the next request should be blocked.

指定者:

shouldBlock 在接口中 RateLimitingStrategy

参数:

requestInfo - Data class containing information on request being sent

getMaxBatchSize

public int getMaxBatchSize()

从接口复制的说明: RateLimitingStrategy

Returns the current max batch size that RateLimitingStrategy will allow through. This is required so that the component that constructs the ResultInfo that is passed into RateLimitingStrategy.shouldBlock(RequestInfo) can construct a passable ResultInfo.

指定者:

getMaxBatchSize 在接口中 RateLimitingStrategy
