Webb20 okt. 2024 · The replication strategy can then place some “smaller” shards together with some “bigger” shards on common replica sets, thus achieving the balancing of partitions across nodes. In other words, the responsibility of load balancing can be shifted between the partitioning scheme and the replication strategy. Webb29 apr. 2024 · Gelvan says that database sharding isn’t the only solution to managing heavy workloads. “The goal is to shard when you want, not when you must,” he says.
