Serialization

The resulting document of a collection is serialized before being written to the file system. This process ensures the document can be stored in a file and later read back into memory. To serialize the document, the resulting object must be serializable, meaning it can only consist of the following types:

• String
• Number
• Boolean
• Null
• Undefined
• Date
• Map
• Set
• BigInt
• Array of serializable types
• Object with serializable values
