I wonder how this new approach compares to serializable snapshot isolation (SSI) https://wiki.postgresql.org/wiki/SSI

I'm not familiar with these technologies, but when I was studying databases, SSI was touted as the "better" 2PL on the horizon. I wonder how SSI compares to 2PLSF, and why it wasn't mentioned here?

I’m working on a memory model for a new platform which is almost entirely based around copy on write, snapshots and SSI. But in distributed effects you still need locks and two phase transactions and so on. These are largely complementary features imo.
