Serialization in OrientDb

Question

When I create a Document and save it in OrientDb using java.Does the saving the document and retrieving the document includes Serialization or marshalling.If not is there any new technique used by OrientDb?Is the new Technique better than serialization in terms of time taken to insert and retrieve?

Answer 1

Serialization is the process to convert objects to a byte array (or better to a sequence of bits). (Serialization and marshalling are different terms to show the same process. See wikipedia)

If you need to save objects in any form (database, file, stream) you need to serialize them.

OrientDb has its own implementation to serialize and deserialize objects. They uses internal code to do that instead of external libraries to be more efficient and to know exactly how the data are stored.

It is possible to know more about how OrientDb serialize data taking a look to their documentation. I don't know if this is the form of data that are used to save records on the database or only used as network interchange format.
