      The flow control mechanism reduces the number of ticket acquisitions permitted when replication lag reaches a certain threshold. Presently, when replication lag is low, the number of flow control ticket acquisitions permitted is increased too aggressively, leading to oscillations in throughput. Oscillations can be mitigated by tempering the increase in the number of ticket acquisitions when lag is low.
