The investors you refer to typically manage money on behalf of their investors and are actually under constant scrutiny. If they run mutual funds, their performance is measured every day, and if they underperform for a number of quarters in a row, their investors will absolutely “fire” them by withdrawing money from their funds.

You're probably looking for the Arrow IPC format [1], which writes the data in close to the same format as the memory layout. On some platforms, reading this back is just an mmap and can be done with zero copying. Parquet, on the other hand, is a somewhat more complex format and there will be some amount of encoding and decoding on read/write. Flight is an RPC framework that essentially sends Arrow data around in IPC format.
