Hello,
I have question, If you publish stream items onchain. Does the stream item stored onchine or external database like Mysql or MongoDB. Because I'm wondering how multichain stored the stream items and retrieves the data quickly and easliy unlike the ethereum cannot be treated as db. I mean when I want retrieve all stored stream items associated with the speific key, I can retrieve it quickly so I though it does store it on database embdded into multichain , it's not going through the blocks from the begining.
