While not an initial goal, supporting transactional global secondary indexes and supporting non-global modes of operation (i.e. to replace LOCAL_SERIAL for latency sensitive users) are future goals we anticipate enabling with this work.

Initially, supporting the Paxos-based LWT and Accord side by side is also an example of such modularity and optionality.

Non-Goals
