Our use case takes full advantage of these features. Little and big-endian Courtesy of Use Cases for Serialization It is essential that the endianness matches from one system to another or be converted somehow, as not all systems order their bits the same way. You can see the little and big-endian differences below. For serialization to work, the byte stream needs to transfer data types regardless of the changing endianness from one system to another. You can think of memory as a block where bites of data are stored. Endianness is a term used to describe the order of bytes in memory. I’d also like to touch on the subject of endianness lightly. Golang Struct using JSON tags What is Endianness? In Golang, you can give hints called tags, easily converting this object into JSON data using Golang's built-in marshaling service. You can see this struct I created for interacting with Twitter data below as an example of marshaling in action. Both do serialization, but there is a difference in intent in these two processes. In contrast, serialization sends or stores data in a byte stream and reassembles it in its original form. The difference is that marshaling might be used to translate data. For example, when creating a Golang program to read JSON data into a Golang data structure, you might use marshaling to translate JSON key values into Golang key values. Marshaling is the process of transforming the memory representation of an object into a suitable form for transmission.Īlthough marshaling and serialization are loosely synonymous, there is a crucial difference. The process of marshaling might come to mind. Serialization Process Marshaling and Serialization - what are the differences? This cuts down the storage size needed and makes it easier to transfer information over a network. To wit, serialization is the process of converting a data object into a byte stream, and saving the state of the object to be stored on a disk or transmitted across a network. The technical definition is a bit more fun. The message recipient then gets the pieces of the puzzle, puts them all back together, and now they have my message. I take apart the pieces, add some instructions on how to reassemble the puzzle, and send it along. So I write down the text on an already assembled puzzle. Imagine that I need to send a message to someone. Serialization is the process in which one service takes in a data structure, such as a dictionary in Python, wraps it up, and transmits it to another service for reading. I helped my colleague learn about serialization that day, and you’re going to learn about it today. This was the case for this person, as it was for me at one point. It's easy to miss essential processes like these that don’t come up until you dive into more extensive projects. During a recent project update meeting, my team talked about how we were going to use serialization to send data back and forth from this application.Īn engineer who was looking to get more into software projects told me that they were unfamiliar with the term.
