[jira] [Created] (CASSANDRA-21070) Prefix queries on SSTable-attached index

Caleb Rackliffe created CASSANDRA-21070:
-------------------------------------------

             Summary: Prefix queries on SSTable-attached index
                 Key: CASSANDRA-21070
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-21070
             Project: Apache Cassandra
          Issue Type: Improvement
          Components: Feature/SAI
            Reporter: Caleb Rackliffe


If the current on-disk trie supports payloads on internal nodes of the trie, we may be able to support prefix queries reasonably efficiently. However, given that would not give us perfect coverage of the postings space, we should probably still start by building a "slow" version of this that just gathers and sorts matches from leaf nodes.
