2. 5:51Reasons to rewrite - functional changes Original system written for a single specific cloud storage provider, the new one should work with multiple storage providers Different file upload protocols (FTP vs. HTTP) Database polling to be fully replaced with message queues
3. 8:12Reasons to rewrite-revised design goals - Avoid manual thread management Strict mutability control Enforced component isolation • Replace general-purpose programming model with the one tailored for message processing • Better exploit functional transformations
4. 14:05Why F#? Just say "no" to mutable variables! Idiomatic F# API, actors as functions without any internal state *An actor in F# can be implemented as a finite state machine with each state managed by its own function • F# is made for functional transformations! •Less ceremony, more compact code
