Name | Default Value | Description |
|---|
keepAlive
| true
| Setting to ensure socket is not closed due to inactivity |
tcpNoDelay
| true
| Setting to improve TCP protocol performance |
backlog
| | Allows to configure a backlog for netty consumer (server). Note the backlog is just a best effort depending on the OS. Setting this option to a value such as 200, 500 or 1000, tells the TCP stack how long the "accept" queue can be. If this option is not configured, then the backlog depends on OS setting. |
broadcast
| false
| Setting to choose Multicast over UDP |
connectTimeout
| 10000
| Time to wait for a socket connection to be available. Value is in millis. |
reuseAddress
| true
| Setting to facilitate socket multiplexing |
sync
| true
| Setting to set endpoint as one-way or request-response |
synchronous
| false
| By default, the Asynchronous Routing Engine is used. Set to true to force processing synchronously. |
ssl
| false
| Setting to specify whether SSL encryption is applied to this endpoint |
sslClientCertHeaders
| false
| When enabled and in SSL mode, then the Netty consumer will enrich the Camel Message with headers having information about the client certificate such as subject name, issuer name, serial number, and the valid date range. |
sendBufferSize
| 65536 bytes
| The TCP/UDP buffer sizes to be used during outbound communication. Size is bytes. |
receiveBufferSize
| 65536 bytes
| The TCP/UDP buffer sizes to be used during inbound communication. Size is bytes. |
option.XXX
| null
| Allows to configure additional netty options using "option." as prefix. For example "option.child.keepAlive=false" to set the netty option "child.keepAlive=false". See the Netty documentation for possible options that can be used. |
corePoolSize
| 10
| The number of allocated threads at component startup. Defaults to 10. Note: This option is removed from Camel 2.9.2 onwards. As we rely on Nettys default settings. |
maxPoolSize
| 100
| The maximum number of threads that may be allocated to this endpoint. Defaults to 100. Note: This option is removed from Camel 2.9.2 onwards. As we rely on Nettys default settings. |
disconnect
| false
| Whether or not to disconnect(close) from Netty Channel right after use. Can be used for both consumer and producer. |
lazyChannelCreation
| true
| Channels can be lazily created to avoid exceptions, if the remote server is not up and running when the Camel producer is started. |
transferExchange
| false
| Only used for TCP. You can transfer the exchange over the wire instead of just the body. The following fields are transferred: In body, Out body, fault body, In headers, Out headers, fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. |
| false | Camel 2.18 Only used for TCP when transferExchange is true. Serializable objects in In/Out headers and exchange properties are transfered. |
disconnectOnNoReply
| true
| If sync is enabled then this option dictates NettyConsumer if it should disconnect where there is no reply to send back. |
noReplyLogLevel
| WARN
| If sync is enabled this option dictates NettyConsumer which logging level to use when logging a there is no reply to send back. Values are: FATAL, ERROR, INFO, DEBUG, OFF. |
serverExceptionCaughtLogLevel
| WARN
| If the server (NettyConsumer) catches an exception then its logged using this logging level. |
serverClosedChannelExceptionCaughtLogLevel
| DEBUG
| If the server (NettyConsumer) catches an java.nio.channels.ClosedChannelException then its logged using this logging level. This is used to avoid logging the closed channel exceptions, as clients can disconnect abruptly and then cause a flod of closed exceptions in the Netty server. |
allowDefaultCodec
| true
| The netty component installs a default codec if both, encoder/deocder is null and textline is false. Setting allowDefaultCodec to false prevents the netty component from installing a default codec as the first element in the filter chain. |
textline
| false
| Only used for TCP. If no codec is specified, you can use this flag to indicate a text line based codec; if not specified or the value is false, then Object Serialization is assumed over TCP. |
delimiter
| LINE
| The delimiter to use for the textline codec. Possible values are LINE and NULL. |
decoderMaxLineLength
| 1024
| The max line length to use for the textline codec. |
autoAppendDelimiter
| true
| Whether or not to auto append missing end delimiter when sending using the textline codec. |
encoding
| null
| The encoding (a charset name) to use for the textline codec. If not provided, Camel will use the JVM default Charset. |
workerCount
| 0null
| When netty works on nio mode and workerCount is 0, it uses default workerCount parameter from Netty, which is cpu_core_threads*2. User can use this operation to override the default workerCount from Netty. |
sslContextParameters
| null
| SSL configuration using an org.apache.camel.util.jsse.SSLContextParameters instance. See Using the JSSE Configuration Utility. |
receiveBufferSizePredictor
| null
| Configures the buffer size predictor. See details at Jetty documentation and this mail thread. |
requestTimeout
| 0
| Allows to use a timeout for the Netty producer when calling a remote server. By default no timeout is in use. The value is in milli seconds, so eg 30000 is 30 seconds. The requestTimeout is using Netty's ReadTimeoutHandler to trigger the timeout. Camel 2.16, 2.15.3 you can also override this setting by setting the CamelNettyRequestTimeout header. |
needClientAuth
| false
| Configures whether the server needs client authentication when using SSL. |
usingExecutorService
| true
| Whether to use executorService to handle the message inside the camel route, the executorService can be set from NettyComponent. |
maximumPoolSize
| 16
| The core pool size for the ordered thread pool, if its in use. NOTE: you can just setup this on the NettyComponent level since Camel 2.15, 2.14.1. |
producerPoolEnabled
| true
| Producer only. Whether producer pool is enabled or not. Important: Do not turn this off, as the pooling is needed for handling concurrency and reliable request/reply. |
producerPoolMaxActive
| -1
| Producer only. Sets the cap on the number of objects that can be allocated by the pool (checked out to clients, or idle awaiting checkout) at a given time. Use a negative value for no limit. |
producerPoolMinIdle
| 0
| Producer only. Sets the minimum number of instances allowed in the producer pool before the evictor thread (if active) spawns new objects. |
producerPoolMaxIdle
| 100
| Producer only. Sets the cap on the number of "idle" instances in the pool. |
producerPoolMinEvictableIdle
| 300000
| Producer only. Sets the minimum amount of time (value in millis) an object may sit idle in the pool before it is eligible for eviction by the idle object evictor. |
bootstrapConfiguration
| null
| Consumer only. Allows to configure the Netty ServerBootstrap options using a org.apache.camel.component.netty4.NettyServerBootstrapConfiguration instance. This can be used to reuse the same configuration for multiple consumers, to align their configuration more easily. |
bossGroup
| null
| To use a explicit io.netty.channel.EventLoopGroup as the boss thread pool. For example to share a thread pool with multiple consumers. By default each consumer has their own boss pool with 1 core thread. |
workerGroup
| null
| To use a explicit io.netty.channel.EventLoopGroup as the worker thread pool. For example to share a thread pool with multiple consumers or producers. By default each consumer or producer has their own worker pool with 2 x cpu count core threads. |
| channelGroup | null | Camel 2.17 To use a explicit io.netty.channel.group.ChannelGroup for example to broadact a message to multiple channels. |
networkInterface | null
| Consumer only. When using UDP then this option can be used to specify a network interface by its name, such as eth0 to join a multicast group. |
clientInitializerFactory | null | Camel 2.15: To use a custom client initializer factory to control the pipelines in the channel. See further below for more details. |
serverInitializerFactory | null | Camel 2.15: To use a custom server initializer factory to control the pipelines in the channel. See further below for more details. |
clientPipelineFactory
| null | Deprecated: Use clientInitializerFactory instead. |
serverPipelineFactory
| null | Deprecated: Use serverInitializerFactory instead. |
udpConnectionlessSending
| false
| Camel 2.15: Producer only. This option supports connection less udp sending which is a real fire and forget. A connected udp send receive the PortUnreachableException if no one is listen on the receiving port. |
clientMode | false | Camel 2.15: Consumer only. If the clientMode is true, netty consumer will connect the address as a TCP client. |
reconnect | true | Camel 2.16: Consumer only. Used only in clientMode in consumer, the consumer will attempt to reconnect on disconnection automatically. |
reconnectInterval | 10000 | Camel 2.16: Consumer only. Used if reconnect and clientMode is enabled. The interval in milli seconds to attempt reconnection. |
useByteBuf
| false | Camel 2.16: Producer only. If the useByteBuf is true, netty producer will turn the message body into ByteBuf before sending it out. |
udpByteArrayCodec
| false | Camel 2.16: When using UDP protocol then turning this option to true sends the data as a byte array instead of the default object serialization codec. |
reuseChannel | false | Camel 2.17: Producer only. This option allows producers to reuse the same Netty Channel for the lifecycle of processing the Exchange. This is useable if you need to call a server multiple times in a Camel route and want to use the same network connection. When using this the channel is not returned to the connection pool until the Exchange is done; or disconnected if the disconnect option is set to true.
The reused Channel is stored on the Exchange as an exchange property with the key NettyConstants#NETTY_CHANNEL which allows you to obtain the channel during routing and use it as well. |
nativeTransport | false | Camel 2.18: Whether to use native transport instead of NIO. Native transport takes advantage of the host operating system and is only supported on some platforms. You need to add the netty JAR for the host operating system you are using. See more details at: http://netty.io/wiki/native-transports.html |
