Class LimitedPriorityLevelConfiguration

  • All Implemented Interfaces:
    com.marcnuri.yakc.model.Model
    public class LimitedPriorityLevelConfiguration
extends java.lang.Object
implements com.marcnuri.yakc.model.Model
    LimitedPriorityLevelConfiguration specifies how to handle requests that are subject to limits. It addresses two issues:

    - How are requests for this priority level limited?

    - What should be done with requests that exceed the limit?

      • getBorrowingLimitPercent

        public java.lang.Number getBorrowingLimitPercent()
        `borrowingLimitPercent`, if present, configures a limit on how many seats this priority level can borrow from other priority levels. The limit is known as this level's BorrowingConcurrencyLimit (BorrowingCL) and is a limit on the total number of seats that this level may borrow at any one time. This field holds the ratio of that limit to the level's nominal concurrency limit. When this field is non-nil, it must hold a non-negative integer and the limit is calculated as follows.


        BorrowingCL(i) = round( NominalCL(i) * borrowingLimitPercent(i)/100.0 )


        The value of this field can be more than 100, implying that this priority level can borrow a number of seats that is greater than its own nominal concurrency limit (NominalCL). When this field is left `nil`, the limit is effectively infinite.

      • getLendablePercent

        public java.lang.Number getLendablePercent()
        `lendablePercent` prescribes the fraction of the level's NominalCL that can be borrowed by other priority levels. The value of this field must be between 0 and 100, inclusive, and it defaults to 0. The number of seats that other levels can borrow from this level, known as this level's LendableConcurrencyLimit (LendableCL), is defined as follows.


        LendableCL(i) = round( NominalCL(i) * lendablePercent(i)/100.0 )

      • getNominalConcurrencyShares

        public java.lang.Number getNominalConcurrencyShares()
        `nominalConcurrencyShares` (NCS) contributes to the computation of the NominalConcurrencyLimit (NominalCL) of this level. This is the number of execution seats available at this priority level. This is used both for requests dispatched from this priority level as well as requests dispatched from other priority levels borrowing seats from this level. The server's concurrency limit (ServerCL) is divided among the Limited priority levels in proportion to their NCS values:


        NominalCL(i) = ceil( ServerCL * NCS(i) / sum_ncs ) sum_ncs = sum[priority level k] NCS(k)


        Bigger numbers mean a larger nominal concurrency limit, at the expense of every other priority level. This field has a default value of 30.

      • setBorrowingLimitPercent

        public void setBorrowingLimitPercent​(java.lang.Number borrowingLimitPercent)
        `borrowingLimitPercent`, if present, configures a limit on how many seats this priority level can borrow from other priority levels. The limit is known as this level's BorrowingConcurrencyLimit (BorrowingCL) and is a limit on the total number of seats that this level may borrow at any one time. This field holds the ratio of that limit to the level's nominal concurrency limit. When this field is non-nil, it must hold a non-negative integer and the limit is calculated as follows.


        BorrowingCL(i) = round( NominalCL(i) * borrowingLimitPercent(i)/100.0 )


        The value of this field can be more than 100, implying that this priority level can borrow a number of seats that is greater than its own nominal concurrency limit (NominalCL). When this field is left `nil`, the limit is effectively infinite.

        public void setLimitResponse​(LimitResponse limitResponse)

      • setNominalConcurrencyShares

        `nominalConcurrencyShares` (NCS) contributes to the computation of the NominalConcurrencyLimit (NominalCL) of this level. This is the number of execution seats available at this priority level.
