java.lang.Object

java.lang.Record

io.micronaut.http.netty.channel.loom.LoomCarrierConfiguration

Record Components:

timeSliceLatency - Time slice size in latency mode.

timeSliceThroughput - Time slice size in throughput mode.

fifoSwitchTime - Number of nanoseconds between switching between continuation FILO and FIFO modes.

taskFifoThreshold - Oldest enqueued continuation must be this old before execution can switch to FIFO mode.

blockTime - Maximum blocking wait time.

throughputModeThreshold - Maximum number of queued tasks before entering throughput mode.

workSpillThreshold - Maximum number of threads per event loop before work spilling should kick in.

normalWarmupTasks - Number of tasks that should run on the normal FJP to initialize e.g. the Poller before switching to the netty scheduler

public record LoomCarrierConfiguration(Duration timeSliceLatency, Duration timeSliceThroughput, Duration fifoSwitchTime, Duration taskFifoThreshold, Duration blockTime, int throughputModeThreshold, int workSpillThreshold, int normalWarmupTasks)
extends Record

Configuration properties for the netty-based virtual thread scheduler. These properties are experimental and subject to change as the scheduler evolves, even in patch releases.

Creates an instance of a LoomCarrierConfiguration record class.

Parameters:

timeSliceLatency - the value for the timeSliceLatency record component

timeSliceThroughput - the value for the timeSliceThroughput record component

fifoSwitchTime - the value for the fifoSwitchTime record component

taskFifoThreshold - the value for the taskFifoThreshold record component

blockTime - the value for the blockTime record component

throughputModeThreshold - the value for the throughputModeThreshold record component

workSpillThreshold - the value for the workSpillThreshold record component

normalWarmupTasks - the value for the normalWarmupTasks record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.
