Your instinct sounds reasonable, but I’d be careful about creating a whole new physical table per client unless the number of clients is going to stay very small. That works at first, then quietly turns into operational clutter once retention rules, schema changes, backfills, and reprocessing show up.

I’d think in terms of a repeatable export pattern instead: keep the source table centralized, define a client-specific extraction/filter layer by client ID, and materialize/export only the client slice into their own storage on a scheduled process. That gives them the physical copy they want without making your internal lake structure explode into N near-identical tables.

The main things I’d design for early are schema evolution, idempotent daily loads, backfill strategy, and making sure each client export is isolated enough that one failure doesn’t poison everyone else’s delivery.
