> In order to avoid rebuilding indexes when no columns are actually indexed (originally implemented in CASSANDRA-9196), CASSANDRA-9281 hinted at overriding {{SecondaryIndex#getColumnDefs}} to "filter out" indexes that shouldn't be rebuilt; unfortunately, I believe this would be quite wrong for safety reasons, as it could have side effects on other methods relying on {{getColumnDefs}} returning a stable set, and API consistency ones, as it would be confusing to have {{getColumnDefs}} behave differently based on runtime conditions, possibly ignoring {{addColumnDef}} calls.
> I believe {{SecondaryIndex#indexes}} is still the best candidate to act as a filter predicate, and I propose to overload it to accept a column definition name for all those cases (i.e. index rebuilding) missing a full cell name.
