Abstract: According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that, when executed by the processor, may cause the processor to receive event data to be placed in a plurality of queues. The processor may determine logical partitions for the received event data and may store the event data in the plurality of queues based on the determined logical partitions. A first queue of the plurality of queues may be mapped to a first logical partition range and a second queue of the plurality of queues may be mapped to a second logical partition range. Based on respective loads at the plurality of queues, the processor may update a mapping of the determined logical partitions to the plurality of queues by transferring logical partitions between the first queue and the second queue.
