极限网关核心架构解析：从 Nginx 到 INFINI Gateway 的演进
The application-layer INFINI Gateway is especially designed for Elasticsearch and offers powerful features.
应用层INFINI Gateway是专门为Elasticsearch设计的，提供了强大的功能。
High availability: The gateway supports non-stop indexing and is capable of automatically processing faults occurring on Elasticsearch, without affecting normal data ingestion.
高可用性：该网关支持不间断索引，能够自动处理Elasticsearch上发生的故障，而不会影响正常的数据摄取。
Write acceleration: The gateway can automatically merge independent index requests into a bulk request, thereby reducing back-end pressure and improving indexing efficiency.
写入加速：网关可以自动将独立的索引请求合并为批量请求，从而减轻后端压力，提高索引效率。
Query acceleration: Query cache can be configured on INFINI Gateway and Kibana dashboards can accelerate the query seamlessly and intelligently to fully enhance search experience.
查询加速：查询缓存可以在INFINI Gateway上配置，Kibana仪表板可以无缝和智能地加速查询，以全面提升搜索体验。
Seamless retry: The gateway automatically processes faults occurring on Elasticsearch, and migrates and retries query requests.
无缝重试：网关自动处理Elasticsearch上发生的错误，并迁移和重试查询请求。
Traffic cloning: The gateway can replicate traffic to multiple different Elasticsearch clusters and supports traffic migration through canary deployment.
流量克隆：网关可以将流量复制到多个不同的Elasticsearch集群，并通过金丝雀部署支持流量迁移。
One-click rebuilding: The optimized high-speed index rebuilding and automatic processing of incremental data enable the gateway to seamlessly switch between old and new indexes.
一键重建：优化的高速索引重建和增量数据的自动处理使网关能够在新旧索引之间无缝切换。
Secure transmission: The gateway supports the Transport Layer Security (TLS) and Hypertext Transfer Protocol Secure (HTTPS) protocols. It can automatically generate certification files and supports specified trust certification files.
安全传输：网关支持传输层安全（TLS）和超文本传输协议安全（HTTPS）协议。可以自动生成认证文件，支持指定的信任认证文件。
Precision routing: The gateway supports the load balancing mode using multiple algorithms, in which load routing strategies can be separately configured for indexing and query, providing great flexibility.
精密布线：网关支持多种算法的负载均衡模式，索引和查询分别配置负载路由策略，灵活性强。
Traffic control and throttling: Multiple traffic control and throttling rules can be configured to implement index-level traffic control and ensure the stability of back-end clusters.
流量控制和节流：支持配置多种流量控制和节流规则，实现索引级流量控制，保证后端集群稳定。
Concurrency control: The gateway can control cluster- and node-level concurrent TCP connections to ensure the stability of back-end clusters and nodes.
并发控制：网关可以控制集群级和节点级的并发TCP连接，以确保后端集群和节点的稳定性。
No single point of failure (SPOF): The built-in virtual IP-based high availability solution supports dual-node hot standby and automatic failover to prevent SPOFs.
无单点故障（SPOF）：内置的基于虚拟IP的高可用性解决方案支持双节点热备和自动故障转移，以防止SPOF。
Request observability: The gateway is equipped with the logging and indicator monitoring features to fully analyze Elasticsearch requests.
请求可观察性：网关配备了日志记录和指标监控功能，可以全面分析Elasticsearch请求。
