Hi, my question is let’s say because of a network partition between a node and all other nodes in the system, this node could not communicate with any other nodes, but the load balancer was able to communicate with this node and we are using a load balancer to get the data from the client side, and the load balancer sends the request to the node which is not able to talk to other nodes but can communicate to the load balancer and this node does not contain the data the client is requesting for, what will happen if this happens?
Hi @Arun_AP ,
Thanks for contacting us via your query.
If a network partition occurs and a node becomes isolated from the rest of the system, there are a few different things that could happen depending on the specific details of your system and how it’s configured.
If the load balancer is able to communicate with the isolated node, but the node does not contain the data that the client is requesting, the load balancer may return an error or a message indicating that the data is not available. This would likely depend on the specific load balancer and its configuration.
If the load balancer is not able to detect that the node is isolated and continues to forward requests to it, the client may experience a delay while waiting for a response. This could happen if, for example, the load balancer is using a health check mechanism that is not able to detect that the node is down.
If the load balancer is able to detect that the node is isolated and can route the requests to other available nodes, the client will be able to get the data. But in case the node isolated contains certain critical information that other nodes don’t have, and it’s not able to replicate it, that information may be unavailable until the partition is resolved.
Hope the answer to your query.
