> An on-disk index for string (literal) datatypes. This index is used for the following datatypes:
>  * `UTF8Type`
>  * `AsciiType`
>  * `CompositeType`
>  * Frozen types
> This includes the ability to write the index to disk at index creation, by specific index rebuild and during SSTable compaction. 
> Also the ability to query the on-disk index and combine the results with those from the in-memory indexes created by CASSANDRA-18058.
