Problems solved by technology

[0014] 6) Since TCP is implemented in the operating system kernel and middleware firmware, it is almost impossible to make major changes to TCP
[0015] Since the QUIC protocol is very complex, even more complex than HTTP / 2, the client is more complicated to implement
In addition, due to the use of the UDP protocol, the support for UDP channels in the network is insufficient and unstable

[0040] Inspur Yunhai distributed database DRDB is a cloud-native distributed NewSQL database. After each node in the database cluster is started, a network connection needs to be established to complete database business functions such as node interconnection, heartbeat detection, and replica migration. When establishing a network connection, the gRPC ...

Abstract

The invention particularly relates to an application of a quick interconnection protocol QUIC in a distributed database system. According to the application of the quick interconnection protocol QUICin the distributed database system, when nodes in a database cluster perform network interconnection to transmit service data, the QUIC protocol is used for connection, and a gRPC server node monitorsa network address based on the QUIC protocol, receives application data when the data arrives and replies a response; and a gRPC client node establishes QUIC protocol connection with the gRPC serverthrough dialing, sends application data through a QUIC channel and waits for response, thereby improving the node connection speed and saving the overhead of system resources. According to the application of the quick interconnection protocol QUIC in the distributed database system, when nodes in a database cluster are increased on a large scale, network connection between the nodes can be established quickly, the expenditure of system resources is effectively reduced, and stable operation and quick capacity expansion of the distributed database system are guaranteed.

Description

technical field [0001] The invention relates to the technical field of distributed database systems, in particular to the application of a fast interconnection protocol QUIC in distributed database systems. Background technique [0002] QUIC (Quick UDP Internet Connection) is a UDP-based low-latency Internet transport layer protocol. QUIC is a good solution to the various needs faced by the transport layer and application layer today, including handling more connections, security and low latency. QUIC integrates the features of protocols including TCP, TLS, HTTP / 2, etc. but is based on UDP transmission, so it is fast and takes up less resources. Based on UDP transmission, it means lighter weight and much less error checking. Means higher efficiency. [0003] Specifically, the advantages of QUIC are as follows: [0004] 1) The establishment of a low-latency connection. For traditional HTTPS, the TCP handshake at the transport layer requires 3 RTTs (Round-Trip Time: round-t...
