We can only push down a single qual to Redis, which must use the TEXTEQ operator, and must be on the key column. There is currently no support for non.scalar datatypes in Redis such as lists. Usage.

Since the Nix package manager always stores components next to each other in a Nix store and never overwrites existing files, upgrading a distributed system is very safe and we can almost always perform a rollback. The only impure step while upgrading, is the activation of obsolete services and activation of newly installed services, a phase in which users may observe that the system is changing.
