Phoenix "LIKE 'query%' " performance

[Cheyenne Forbes]

   - Can it be fast?
   - does it use the Hbase regex feature?
   - how can I make it case insensitive? so when I do "LIKE 'query%' " the
   results include "Query"
   - Can I get millisecond results using "WHERE column LIKE" on a large
   table? couple terabytes of data
   - is it recommended
