"LimitedPriorityLevelConfiguration specifies how to handle requests that are subject to limits. It addresses two issues:\n * How are requests for this priority level limited?\n * What should be done with requests that exceed the limit?"



fn withAssuredConcurrencyShares


"assuredConcurrencyShares (ACS) configures the execution limit, which is a limit on the number of requests of this priority level that may be exeucting at a given time. ACS must be a positive number. The server's concurrency limit (SCL) is divided among the concurrency-controlled priority levels in proportion to their assured concurrency shares. This produces the assured concurrency value (ACV) --- the number of requests that may be executing at a time --- for each such priority level:\n\n ACV(l) = ceil( SCL * ACS(l) / ( sum[priority levels k] ACS(k) ) )\n\nbigger numbers of ACS mean more reserved concurrent requests (at the expense of every other PL). This field has a default value of 30."

obj limitResponse

"LimitResponse defines how to handle requests that can not be executed right now."

fn limitResponse.withType


"type is \"Queue\" or \"Reject\". \"Queue\" means that requests that can not be executed upon arrival are held in a queue until they can be executed or a queuing limit is reached. \"Reject\" means that requests that can not be executed upon arrival are rejected. Required."

obj limitResponse.queuing

"QueuingConfiguration holds the configuration parameters for queuing"

fn limitResponse.queuing.withHandSize


"handSize is a small positive number that configures the shuffle sharding of requests into queues. When enqueuing a request at this priority level the request's flow identifier (a string pair) is hashed and the hash value is used to shuffle the list of queues and deal a hand of the size specified here. The request is put into one of the shortest queues in that hand. handSize must be no larger than queues, and should be significantly smaller (so that a few heavy flows do not saturate most of the queues). See the user-facing documentation for more extensive guidance on setting this field. This field has a default value of 8."

fn limitResponse.queuing.withQueueLengthLimit


"queueLengthLimit is the maximum number of requests allowed to be waiting in a given queue of this priority level at a time; excess requests are rejected. This value must be positive. If not specified, it will be defaulted to 50."

fn limitResponse.queuing.withQueues


"queues is the number of queues for this priority level. The queues exist independently at each apiserver. The value must be positive. Setting it to 1 effectively precludes shufflesharding and thus makes the distinguisher method of associated flow schemas irrelevant. This field has a default value of 64."
