-------------------------------------------
Summary: Support EQ/PREFIX queries in CONTAINS mode without
tokenization by augmenting SA metadata per term
Key: CASSANDRA-11434
URL: https://issues.apache.org/jira/browse/CASSANDRA-11434
Project: Cassandra
Issue Type: Improvement
Components: sasi
Reporter: Pavel Yaskevich
Assignee: Jordan West
Fix For: 3.6
We can support EQ/PREFIX requests to CONTAINS indexes by tracking "partiality"
of the data stored in the OnDiskIndex and IndexMemtable, if we know exactly if
current match represents part of the term or it's original form it would be
trivial to support EQ/PREFIX since PREFIX is subset of SUFFIX matches.
Since we attach uint16 size to each term stored we can take advantage of sign
bit so size of the index is not impacted at all.
