BSON and Data Interchange` BSON is a binary representation of JSON designed to improve data interchange, allowing for faster scanning and easier manipulation of large documents. Its primary goals are fast scan-ability, easy manipulation, and additional data types such as a byte array type, which eliminates the need for base64 encoding. BSON was developed by MongoDB and is now a separate specification, with open-source implementations available under various licenses. The format has gained widespread adoption in the industry and is widely used in MongoDB projects, including sending documents over the network, persisting them to disk, and internal data manipulations.
