One of the biggest pains with MongoDB has been handling problems caused by picking bad shard keys when sharding to scale out horizontally as your application needs and data size grow. Suboptimal shard keys cause performance problems relating to disk imbalance, disk I/O, and issues with CPU and memory.

MongoDB first addressed this with refinable shard keys in v4.4 and now with live resharding in v5.0.  This highly requested feature took time, effort, changes to the core server and WiredTiger engine. However, it is not all magic and healthy bunnies coming out of the hat. Let’s take a deeper look.
