Jason Rutherglen commented on CASSANDRA-3147:
---------------------------------------------
Jake, I think we can do a polymorphic base class. Then create two different
kinds of index interfaces, row level and column level. The
SecondaryIndexManager will then do an instance of.
> Add rowlevel support to secondary index API and methods need to throw
> exceptions

> The new secondary index API needs to throw IOException on some of the methods
> (where they're missing).
> For index types that index an entire row (like lucene) we need to change the
> api to handle one instance of the index per ColumnFamily. This can be done
> by adding a isRowLevelIndex() method. When the index manager sees this it
> will add all columns of the same index class to the same index instance. and
> on search it will send the entire row to the class vs updating each column.
