The Ultimate Guide to High Availability with MariaDB

Session Resource

Session Resource

A session is an abstraction of a client connection, any number of related backend connections, a router module session and possibly filter module sessions. Each session is created on a service and each service can have multiple sessions.

Resource Operations

Get a session

GET /v1/sessions/:id

Get a single session. :id must be a valid session ID. The session ID is the same that is exposed to the client as the connection ID.

This endpoint also supports the rdns=true parameter, which instructs MaxScale to perform reverse DNS on the client IP address. As this requires communicating with an external server, the operation may be expensive.
