Redis Client Connections

Redis accepts connections on the configured listener TCP port and UNIX socket client, if enabled. When a new client connection is accepted, the following actions are performed:

• Client sockets are placed in a non-blocking state because Redis uses multiplexing and non-blocking I/O operations.

• The Tcp_nodelay option is set to ensure that we do not have a connection delay.

• When creating a readable file, Redis is able to collect the client's query as soon as the new data is available for reading in the socket.

Maximum number of clients

The Redis configuration (redis.conf) property calls MaxClients, which describes the maximum number of clients that can connect to Redis. The basic syntax of the command is:

Config get maxclients1) "MaxClients" 2) "10000"

By default, this property is set to 10000 (which depends on the maximum number of file descriptor limits for the operating system), but you can change this property.

Example

In the example given below, we set the maximum number of clients to 100,000 when starting the server

Redis-server--maxclients 100000
