Constructor Details

DefaultEventLoopGroupConfiguration

@ConfigurationInject
public DefaultEventLoopGroupConfiguration(@Parameter
 String name,
 @Bindable(defaultValue="0")
 int numThreads,
 @Bindable(defaultValue="1.0")
 double threadCoreRatio,
 @Nullable
 @Nullable Integer ioRatio,
 @Bindable(defaultValue="false")
 boolean preferNativeTransport,
 @Nullable
 @Nullable String executor,
 @Nullable
 @Nullable Duration shutdownQuietPeriod,
 @Nullable
 @Nullable Duration shutdownTimeout,
 @Bindable(defaultValue="false")
 boolean loomCarrier)

Default constructor.

Parameters:

name - The name of the group

numThreads - The number of threads

threadCoreRatio - The number of threads per core to use if getNumThreads() is set to 0.

ioRatio - The IO ratio (optional)

preferNativeTransport - Whether native transport is to be preferred

executor - A named executor service to use for event loop threads (optional). This property is very specialized. In particular, it will not solve read timeouts or fix blocking operations on the event loop, in fact it may do the opposite. Don't use unless you really know what this does.

shutdownQuietPeriod - The shutdown quiet period

shutdownTimeout - The shutdown timeout (must be >= shutdownQuietPeriod)

loomCarrier - When set to true, use a special experimental event loop that can also execute virtual threads, in order to improve virtual thread performance.
