Smart client handoffs

Enable Smart client handoffs for your Redis Enterprise Software cluster.

Redis Enterprise Software

Smart client handoffs (SCH) is a feature of Redis Cloud and Redis Enterprise servers that lets them actively notify clients about planned server maintenance shortly before it happens. This lets a client reconnect or otherwise respond gracefully without significant interruptions in service. See Smart client handoffs for more information about SCH.

Note:
SCH is supported only for rolling upgrades.

To enable SCH on a Redis Enterprise server, you must use the /v1/cluster REST API request to set the client_maint_notifications option to true. The example below shows how to do this using the curl command line utility:

curl -k -X PUT -H "accept: application/json" \
    -H "content-type: application/json" \
    -u "<username>:<password>" \
    -d '{ "client_maint_notifications": true }' \
    https://<host>:<port>/v1/cluster
