MariaDB: is Aria's page cache and InnoDB's buffer pool shared across database connections for an embedded database?

If each thread in a multi-threaded application connects to an embedded database, will these threads share a buffer pool when using the InnoDB engine? Will they share a page cache when using the Aria engine? Or does each thread get a private buffer pool / page cache?

Answer Answered by Daniel Black in this comment.

Both InnoDB buffer pool and Aria page cache are a shared instance between all threads.
