Kryo is a fast and efficient binary object graph serialization framework for Java with an easy-to-use API. It also supports automatic deep and shallow object copying without going through bytes.
Use cases
- serialize java objects to binary for persistence
- send objects over the network efficiently
- deep clone object graphs in java
- reduce serialized payload size
- fast serialization for caching or messaging
When to choose
- you need high-performance binary serialization on the JVM
- you want automatic serialization of arbitrary object graphs
- you need direct deep/shallow object cloning
When to avoid
- you need human-readable or cross-language formats like JSON or protobuf
- you require strict schema evolution and interoperability across platforms
- you serialize untrusted data without careful deserialization limits
