How do big data databases handle the problem of primary key values running out given that the key is not unlimited size?
I was wondering about how big data databases handle the problem of primary key values running out given that the key is not unlimited size. Can you explain that to me?
Sure! Big data databases typically use a technique called sharding to distribute the data across multiple nodes. This allows them to increase the number of available primary keys by using multiple shards, each with their own set of unique primary keys.
