👉 Sharding is a technique in distributed computing where data is divided into multiple smaller pieces, each of which can be treated independently. This allows for the efficient management and processing of large amounts of data by distributing it across multiple servers or nodes, thereby reducing the overall cost and complexity of data storage and retrieval. In sharding, each server or node is responsible for storing a subset of the data that needs to be accessed. The data stored on each server or node is typically organized in a way that allows
