> Currently, the code assumes that we'll only have one 2ndary index per column. This has been reasonable so far but stop being it with CASSANDRA-6382 (you might want to index multiple fields of the same UDT column) and CASSANDRA-7458 (you may want to have one "normal" index an multiple functional index for the same column). So we should consider removing that assumption in the code, which is mainly 2 places:
> # in the schema: each ColumnDefinition only has infos for one index. This part should probably be tackled in CASSANDRA-6717 so I'm marking this issue as a follow-up of CASSANDRA-6717.
> # in the 2ndary index API: this is the part I'm suggesting we fix in this issue.
