During load process, the same operation are performed on all replicas such as sort and aggregation, which are resource-intensive. Concurrent data load would consume much CPU and memory resources. It's better to perform write process (writing data into MemTable and then data flush) on single replica and synchronize data files to other replicas before transaction finished.
