A memory-efficient technique for performing weighted round-robin load balancing in a distributed computing system is described. In one example of the present disclosure, a system can determine an offset to apply to a list of node identifiers based on a counter value. The system can select a subset of node identifiers from the list of node identifiers based on the offset. The system can then select a node identifier from the subset of node identifiers based on the counter value and a length of the subset of node identifiers. The system can transmit data to a node that corresponds to the node identifier and increment the counter value. The system can repeat this process any number of times to distribute data among a group of nodes in the distributed computing system.
