Apache Doris是基于MPP架构的新一代开源实时数据仓库,使用更方便,性能更高,适用于大数据分析。
FE(Frontend)主要负责元数据的管理、存储,以及查询的解析等
BE(Backend)则主要负责数据的存储、以及查询计划的执行。BE 中的每个节点都存储有数据的多副本,从而保证数据的高可用和高可靠
实例名称 | 端口名称 | 默认端口 | 通讯方向 | 说明 |
---|---|---|---|---|
BE | be_port | 9060 | FE --> BE | BE 上 thrift server 的端口,用于接收来自 FE 的请求 |
BE | webserver_port | 8040 | BE <–> BE | BE 上的 http server 的端口 |
BE | heartbeat_service_port | 9050 | FE --> BE | BE 上心跳服务端口(thrift),用于接收来自 FE 的心跳 |
BE | brpc_port | 8060 | FE <–> BE, BE <–> BE | BE 上的 brpc 端口,用于 BE 之间通讯 |
FE | http_port | 8030 | FE <–> FE,用户 <–> FE | FE 上的 http server 端口 |
FE | rpc_port | 9020 | BE --> FE, FE <–> FE | FE 上的 thrift server 端口,每个fe的配置需要保持一致 |
FE | query_port | 9030 | 用户 <–> FE | FE 上的 mysql server 端口 |
FE | edit_log_port | 9010 | FE <–> FE | FE 上的 bdbje 之间通信用的端口 |
Broker | broker_ipc_port | 8000 | FE --> Broker, BE --> Broker | Broker 上的 thrift server,用于接收请求 |
