> Currently, a table must be marked as immutable, through the
> IMMUTABLE_ROWS=true property specified at creation time. In this case, all
> indexes added to the table are immutable, while without this property, all
> indexes are mutable.
> Instead, we should support a mix of immutable and mutable indexes. We already
> have an INDEX_TYPE field on our metadata row. We can add a new IMMUTABLE
> keyword and specify an index is immutable like this:
> {code}
> CREATE IMMUTABLE INDEX foo ON bar(c2, c1);
> {code}
> It would be up to the application developer to ensure that only columns that
> don't mutate are part of an immutable index (we already rely on this anyway).
