             Summary: CEP-45: Fix mutation tracking range read bugs
                 Key: CASSANDRA-21726
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-21726
             Project: Apache Cassandra
          Issue Type: Bug
          Components: Consistency/Coordination
            Reporter: Ariel Weisberg
            Assignee: Ariel Weisberg


* Fix filtered range reads timing out when reconciliation delivers a mutation for a partition the row filter dropped
* Fix filtered range reads losing partitions that reconciliation made match, across pages and limits
* Fix filtered range reads returning too few rows, or ending paging early, when rows the filter rejects count against the limit
* Fix range reads timing out when a limit is reached inside an open range tombstone
* Fix indexed range reads timing out when reconciliation delivers a key past the end of the index scan
* Fix tracked reads timing out when a mutation they pull arrives as a duplicate
* Fix range reads missing partitions where a node is a full replica of one range and a witness of the next
* Fix follow up range reads missing data when the remaining range spans more than one replica set
* Fix tracked reads on legacy secondary indexes hanging or returning a partition twice when reconciliation delivers a static row
* Fix single partition queries on a static column index returning no rows when they restrict a clustering column
* Fix partition key indexes missing a partition whose static row became live in a later update
* Fix failed or abandoned tracked reads leaking, or releasing twice, the read OpOrder group that flush and compaction wait on
* Fix partition iterator concatenation not closing inputs it never consumed
* Fix an offsets broadcast for a just dropped keyspace killing the stage that processes it
* Add \{{TrackedRangeReadTest}}, which checks tracked range reads against an untracked keyspace holding the same data, replacing the ignored \{{MutationTrackingRangeReadTest}}
* Run range reads and legacy secondary index queries in the randomized multi node tests for mutation tracking and witnesses (\{{MultiNodeTableWalkWithMutationTrackingTest}} and \{{MultiNodeTableWalkWithWitnessesTest}})

Not fixed here: a range read with a per partition limit can still fail with \{{Multiple partitions received}} when its response holds the same partition twice, so those randomized tests use a per partition limit only on single partition reads. Some witness issues are also not addressed although one witness bug fix is included.
