--------------------------------------
Thanks for reviewing.
> StrictLiveness for view row is not handled in AbstractRow
> ---------------------------------------------------------
>
> Key: CASSANDRA-13883
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13883
> Project: Cassandra
> Issue Type: Bug
> Components: Materialized Views
> Reporter: ZhaoYang
> Assignee: ZhaoYang
> Fix For: 3.0.15, 3.11.1, 4.0
>
>
> In {{AbstractRow.hasLiveData(nowInSecond)}}, it doesn't handle
> {{strictLiveness}} introduced in CASSANDRA-11500. The {{DataLimits}} counts
> the expired view row as live data and then the expired view row is purged in
> {{Row.purge()}}. When query with limit, we will get less data.
> {code:title=test to reproduce}
> @Test
> public void testRegularColumnTimestampUpdates() throws Throwable
> {
> createTable("CREATE TABLE %s (" +
> "k int PRIMARY KEY, " +
> "c int, " +
> "val int)");
> execute("USE " + keyspace());
> executeNet(protocolVersion, "USE " + keyspace());
> createView("mv_rctstest", "CREATE MATERIALIZED VIEW %s AS SELECT *
> FROM %%s WHERE k IS NOT NULL AND c IS NOT NULL PRIMARY KEY (k,c)");
> updateView("UPDATE %s SET c = ?, val = ? WHERE k = ?", 0, 0, 0);
> updateView("UPDATE %s SET val = ? WHERE k = ?", 1, 0);
> updateView("UPDATE %s SET c = ? WHERE k = ?", 1, 0);
> assertRows(execute("SELECT c, k, val FROM mv_rctstest"), row(1, 0,
> 1));
> updateView("TRUNCATE %s");
> updateView("UPDATE %s USING TIMESTAMP 1 SET c = ?, val = ? WHERE k =
> ?", 0, 0, 0);
> updateView("UPDATE %s USING TIMESTAMP 3 SET c = ? WHERE k = ?", 1, 0);
> updateView("UPDATE %s USING TIMESTAMP 2 SET val = ? WHERE k = ?", 1,
> 0);
> updateView("UPDATE %s USING TIMESTAMP 4 SET c = ? WHERE k = ?", 2, 0);
> updateView("UPDATE %s USING TIMESTAMP 3 SET val = ? WHERE k = ?", 2,
> 0);
> // FIXME no rows return
> assertRows(execute("SELECT c, k, val FROM mv_rctstest limit 1"),
> row(2, 0, 2));
> assertRows(execute("SELECT c, k, val FROM mv_rctstest"), row(2, 0,
> 2));
> }
> {code}
