Package io.netty.channel.uring

io_uring is a high I/O performance scalable interface for fully asynchronous Linux syscalls. While Netty 4.2 generally requires Java 8 or newer, this optional io_uring native transport requires Java 9 or newer.

Interface Summary

Interface	Description
IoUringBufferRingAllocator	Allocator that is responsible to allocate buffers for a buffer ring.
IoUringIoHandle	IoHandle implementation for io_uring.

Class Summary

Class	Description
AbstractIoUringBufferRingAllocator	Base class for IoUringBufferRingAllocator implementations which support large allocations.
IoUring
IoUringAdaptiveBufferRingAllocator	IoUringBufferRingAllocator implementation which uses an adaptive strategy to allocate buffers, which will decrease / increase the buffer size depending on if the allocated buffers were completely used or not before.
IoUringBufferRingConfig	Configuration class for an IoUringBufferRing.
IoUringBufferRingConfig.Builder
IoUringBufferRingExhaustedEvent	Event that is fired when a read failed because the buffer ring was exhausted for now.
IoUringChannelOption<T>
IoUringDatagramChannel
IoUringDomainSocketChannel	DomainSocketChannel implementation that uses linux io_uring
IoUringFixedBufferRingAllocator	IoUringBufferRingAllocator implementation which uses a fixed size for the buffers that are returned by AbstractIoUringBufferRingAllocator.allocate().
IoUringIoEvent	IoEvent that will be produced as an result of a IoUringIoOps.
IoUringIoHandler	IoHandler which is implemented in terms of the Linux-specific io_uring API.
IoUringIoHandlerConfig	Configuration class for an IoUringIoHandler, managing the settings for a RingBuffer and its io_uring file descriptor.
IoUringIoOps	IoOps for implementation for Io_uring.
IoUringServerDomainSocketChannel
IoUringServerSocketChannel
IoUringSocketChannel
IoUringTcpInfo	struct tcp_info { __u8 tcpi_state; __u8 tcpi_ca_state; __u8 tcpi_retransmits; __u8 tcpi_probes; __u8 tcpi_backoff; __u8 tcpi_options; __u8 tcpi_snd_wscale : 4, tcpi_rcv_wscale : 4; __u32 tcpi_rto; __u32 tcpi_ato; __u32 tcpi_snd_mss; __u32 tcpi_rcv_mss; __u32 tcpi_unacked; __u32 tcpi_sacked; __u32 tcpi_lost; __u32 tcpi_retrans; __u32 tcpi_fackets; __u32 tcpi_last_data_sent; __u32 tcpi_last_ack_sent; __u32 tcpi_last_data_recv; __u32 tcpi_last_ack_recv; __u32 tcpi_pmtu; __u32 tcpi_rcv_ssthresh; __u32 tcpi_rtt; __u32 tcpi_rttvar; __u32 tcpi_snd_ssthresh; __u32 tcpi_snd_cwnd; __u32 tcpi_advmss; __u32 tcpi_reordering; __u32 tcpi_rcv_rtt; __u32 tcpi_rcv_space; __u32 tcpi_total_retrans; };
