Can vouch for the non-triviality of collisions. We have around 500k inserts a second and wanted to have time sensitivity between them (so essentially basic in on a timestamp) and fit it into 64bit unsigned integer. We managed to get a safe space of around 50M per second, so we could safely use shard_id to prevent collisions.
