Benjamin Lerer created CASSANDRA-8147:
-----------------------------------------
Summary: Secondary indexing of map keys does not work properly
when mixing contains and contains_key
Key: CASSANDRA-8147
URL: https://issues.apache.org/jira/browse/CASSANDRA-8147
Project: Cassandra
Issue Type: Bug
Reporter: Benjamin Lerer
Priority: Minor
If you have a table with a map column and an index on the map key selecting
data using a contains key and a contains will not return the expected data.
The problem can be reproduced using the following unit test:
{code}
@Test
public void testMapKeyContainsAndValueContains() throws Throwable
{
createTable("CREATE TABLE %s (account text, id int, categories
map<text,text>, PRIMARY KEY (account, id))");
createIndex("CREATE INDEX ON %s(keys(categories))");
execute("INSERT INTO %s (account, id , categories) VALUES (?, ?, ?)",
"test", 5, map("lmn", "foo"));
assertRows(execute("SELECT * FROM %s WHERE account = ? AND id = ? AND
categories CONTAINS KEY ? AND categories CONTAINS ? ALLOW FILTERING", "test",
5, "lmn", "foo"), row("test", 5, map("lmn", "foo")));
}
{code}
