what exactly is the transaction log? when productionizing, can it be kept in-memory?

No, if you want data to be durable.

Hey @U050S5ZET the log is key to deterministic processing so must be retained indefinitely. It stores the totally ordered sequence of transactions as submitted by submit-tx, however all the data is transformed into hashes before being written and therefore the log doesn't contain any data itself beyond transaction operations, hashes, and timestamps.
