> As part of CASSANDRA-6716 & in anticipation of CASSANDRA-10124, a distinction was introduced between secondary indexes which target a fixed set of 1 or more columns in the base data, and those which are agnostic to the structure of the underlying rows. This distinction is manifested in {{IndexMetadata.targetType}} and {{system_schema.indexes}}, in the {{target_type}} column. It could be argued that this distinction complicates the codebase without providing any tangible benefit, given that the target type is not actually used anywhere.
> It's only the impact on {{system_schema.indexes}} that makes puts this on the critical path for 3.0, any code changes are just implementation details.
