Specialized Type Handlers

Although most types in the JDK or any other Java library will work with MicroStream, there is a bunch of specialized type handlers for the most commonly used types. They are optimized to reduce memory overhead and increase performance.

The following list describes all types for which special type handlers are implemented. All other types are analyzed generically.

Most collections above are handled in a generic way. If you want a more optimized version of JDK collection handlers, you can utilize the provided module microstream-persistence-binary-jdk8.
