1. View.mayBeAffectedBy will return true as long as view-key-values are not
filtered
2. LivenessInfo.supersedes(another) will check localDeletionTime if timestamps
are the same. greater localDeletionTimestamp supersedes.

> Materialized Views: View row expires too soon

> Key: CASSANDRA-13127
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13127
> Project: Cassandra
> Issue Type: Bug
> Components: Local Write-Read Paths, Materialized Views
> Reporter: Duarte Nunes
> Assignee: ZhaoYang
>
> Consider the following commands, ran against trunk:
> {code}
> echo "DROP MATERIALIZED VIEW ks.mv; DROP TABLE ks.base;" | bin/cqlsh
> echo "CREATE TABLE ks.base (p int, c int, v int, PRIMARY KEY (p, c));" |
> bin/cqlsh
> echo "CREATE MATERIALIZED VIEW ks.mv AS SELECT p, c FROM base WHERE p IS NOT
> NULL AND c IS NOT NULL PRIMARY KEY (c, p);" | bin/cqlsh
> echo "INSERT INTO ks.base (p, c) VALUES (0, 0) USING TTL 10;" | bin/cqlsh
> # wait for row liveness to get closer to expiration
> sleep 6;
> echo "UPDATE ks.base USING TTL 8 SET v = 0 WHERE p = 0 and c = 0;" | bin/cqlsh
> echo "SELECT p, c, ttl(v) FROM ks.base; SELECT * FROM ks.mv;" | bin/cqlsh
> p | c | ttl(v)
> ---+---+--------
> 0 | 0 | 7
> (1 rows)
> c | p
> ---+---
> 0 | 0
> (1 rows)
> # wait for row liveness to expire
> sleep 4;
> echo "SELECT p, c, ttl(v) FROM ks.base; SELECT * FROM ks.mv;" | bin/cqlsh
> p | c | ttl(v)
> ---+---+--------
> 0 | 0 | 3
> (1 rows)
> c | p
> ---+---
> (0 rows)
> {code}
> Notice how the view row is removed even though the base row is still live. I
> would say this is because in ViewUpdateGenerator#computeLivenessInfoForEntry
> the TTLs are compared instead of the expiration times, but I'm not sure I'm
> getting that far ahead in the code when updating a column that's not in the
> view.
