These bindings are implemented via Java Native Interface. This interface is more performant than Python, but is not feature complete yet. It mimics native HashMap and Dictionary classes, but has no support for batch operations yet.

DataBase db = new DataBase("");
db.put(42, "purpose of life".getBytes());
assert db.get(42) == "purpose of life".getBytes() : "Big surprise";
db.close();

All get requests cause memory allocations in Java Runtime and export data into native Java types. Most set requests will simply cast and forward values without additional copies. Aside from opening and closing this class is thread-safe for higher interop with other Java-based tools.

Implementation follows the “best practices” defined by IBM.
