> Phoenix allows immutable table with indexes to be overwritten partially as
> long as the indexed columns are not updated during partial overwrites.
> However, there is no check/enforcement for this. The immutable index
> mutations are prepared on the client side without reading the existing data
> table rows. This means the index mutations prepared by the client will be
> partial when the data table row mutations are partial. The new indexing
> design assumes index rows are always full and all cells within an index row
> have the same timestamp. On the read path, GlobalIndexChecker returns only
> the cells with the most recent timestamp of the row. This means that if the
> client updates the same row multiple times, the client will read back only
> the most recent update which could be partial.
