Alejandro Rivero commented on CASSANDRA-5402:
-
To expand on the suggestion; I would expect some kind of column definition as
column_metadata =
[{
column_name : MyIndexedColumn1,
validation_class : IntegerType,
index_type : 99,
index_name : "MyIdxName:0"},
{
column_name : MyIndexedColumn2,
validation_class : UTF8Type,
index_type : 99,
index_name : "MyIdxName:1"}]
And it should produce a secondary index
MyIdxName with a comparator CompositeType(IntegerType, UTF8Type)
> Add secondary indexes on multiple columns.

> Using as index a CompositeType it seems that it should be possible to build a
> secondary index on two or more columns. (If it is already implemented, please
> consider this issue a documentation bug :-)
> A possible way to implement this the old interface is to use the same
> index_name for all the involved columns, or perhaps a combination of
> index_name plus a suffix telling the position of each column in the
> corresponding CompositeType of the index.
