Hash partitioning

Hash partitioning is a method used to organize data across multiple storage locations or systems. It involves applying a mathematical function, called a hash function, to a specific attribute of the data (like a number or text). This function produces a fixed output that determines which partition the data belongs to. For example, if you have a list of users and use their user ID with a hash function, it can help evenly distribute users across several servers or folders. This improves efficiency in data retrieval and management while ensuring a balanced load across resources.
