> Key: CASSANDRA-19461
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19461
> Project: Cassandra
> Issue Type: Bug
> Components: Feature/SAI
> Reporter: Caleb Rackliffe
> Assignee: Caleb Rackliffe
> Priority: Normal
> Fix For: 5.0-rc, 5.x
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> This is easy to reproduce with a test that looks something like this:
> {noformat}
> @Test
> public void testEmptyString()
> {
> createTable("CREATE TABLE %s (k TEXT PRIMARY KEY, v text)");
> createIndex(String.format(CREATE_INDEX_TEMPLATE, 'v'));
> execute("INSERT INTO %s (k, v) VALUES ('0', '')");
> execute("INSERT INTO %s (k) VALUES ('1')");
>
> // flush(); <---- there is not always a memtable index involved, a fix
> will have to pay attention to this
> List<Row> rows = executeNet("SELECT * FROM %s WHERE v = ''").all();
> assertEquals(1, rows.size()); <— FAILS! No matches...
> }
> {noformat}
