Multinode Session allocation

Flosom — Fri, 27 Jan 2023 06:52:53 GMT

Hi,

Could someone clear my doubt on Multinode enviroments.

Is the user sessions allocated to each node in round robin method or are all sessions given to central node first & then pushed to worker nodes?

How does Qlik allocate the user sessions?

thanks in tdvance,

Florence

Hello @Flosom , thank you for posting!

The default algorithm used for load balancing is round-robin, where the load is evenly distributed between the available nodes on the multi-node site. However, any subsequent sessions from the same user/client will open on the current engine node, instead of following the round-robin.
