This scenario exemplifies hot spotting, where the workload is disproportionately concentrated on a few nodes instead of being evenly distributed. In Bigtable, such a situation can arise from row keys that are lexically similar and created in close temporal proximity. Bigtable's write operation distribution is determined by the row key, not by any GCP load balancer. The initial data writing location is unaffected by replication. Being a wide column database, Bigtable can accommodate a vast number of columns, and the quantity of columns does not influence the data distribution across nodes.
