-------------------------------------------
Summary: Optimize initial skipping logic for SAI queries on large
partitions
Key: CASSANDRA-20192
URL: https://issues.apache.org/jira/browse/CASSANDRA-20192
Project: Apache Cassandra
Issue Type: Improvement
Components: Feature/SAI
Reporter: Caleb Rackliffe
CASSANDRA-20100 was a short term fix, and while immediately necessary, papers
over the root of the problem, which is that SAI indexes reversed
byte-comparable values for clustering keys on-disk. We can fix that and make
query construction and post-filtering simpler across the board, but the on-disk
change means we'll have to control the behavior via something like the SAI
segment metadata and an opt-in flag.
