that means multiple put or get operation in same time that is concurrency, and multiple operation happened parallelly that is Parallelism.

Yes, operations run concurrently. They're asynchronously executed in a thread pool. Which may effectively be parallel, given enough free threads. In addition, iterators and streams operate on a snapshot of the database, meaning they're unaffected by concurrent writes.
