Sylvain Lebresne commented on CASSANDRA-3782:
---------------------------------------------
bq. I think it may be confusing that the user would need to specify values for
exactly each part of the PK declaration
I suppose that's more a problem for CASSANDRA-3680. But actually it may be
worth dealing with this at the same time we deal with CASSANDRA-3680. I
initially wanted to separate the two issues because for non-composite wide rows
we wouldn't really need to change anything to secondary indexes to support
this. But now I'm a bit afraid that we'll do something here that is not
coherent with CASSANDRA-3680.

> Currently, CQL 3.0 doesn't allow creating an index on a dynamic CF (with
> COMPACT STORAGE). The goal of this ticket is *not* to support the composite
> case however (CASSANDRA-3680 will tackle this).
> I think changes needed to support this are only in the CQL side and covert
> two area:
> * Finding a syntax for it
> * Currently, the CQL 3 code consider that a CF with any column_metadata
> defined is a non-compact cf. Basically the problem is that we currently use
> column_metadata both for defining a name for a column in the static case, and
> store indexing information. Ideally, we would separate those informations,
> i.e. we could add a new map valueAliases (ByteBuffer -> AbstractType) to
> CFMetadata (only used by static CF) and we would keep column_metadata for
> indexing purpose only. However that may be problematic for backward
> compatibility (with thrift in particular), so probably instead we can just
> add a new boolean isStaticColumnName to ColumnDefinition.
