Benedict created CASSANDRA-8691:
-----------------------------------
Summary: SSTableReader.getPosition() does not correctly filter out
queries that exceed its bounds
Key: CASSANDRA-8691
URL: https://issues.apache.org/jira/browse/CASSANDRA-8691
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Benedict
Fix For: 2.1.3
This has been true for some time, but I worry about including it before 2.1 in
case we depend on the brokenness somehow. In getPosition, we test:
{code}
if (first.compareTo(key) > 0 || last.compareTo(key) < 0)
{
if (op == Operator.EQ && updateCacheAndStats)
bloomFilterTracker.addFalsePositive();
if (op.apply(1) < 0)
{
Tracing.trace("Check against min and max keys allows skipping
sstable {}", descriptor.generation);
return null;
}
}
{code}
However, op.apply(1) always returns >= 0 unless op == Operation.EQ
