---------------------------------
Summary: Inconsistent static column behavior after row deletion
Key: CASSANDRA-8042
URL: https://issues.apache.org/jira/browse/CASSANDRA-8042
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: viasyn
I've a table with static column defined. I'm inserting some rows with TTL
defined, then one of row expires TTL of all the rows with same PK turns into
null:
{{
cqlsh:test> create table tt1 ( c1 text , c2 text , c3 text, cs text static,
PRIMARY KEY (c1, c2) );
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-1', 'x', 's1');
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-2', 'x', 's2');
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-3', 'x', 's3');
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-4', 'x', 's4');
cqlsh:test> select * from tt1;
c1 | c2 | cs | c3
----+-----+----+----
1 | 1-1 | s4 | x
1 | 1-2 | s4 | x
1 | 1-3 | s4 | x
1 | 1-4 | s4 | x
(4 rows)
cqlsh:test> delete from tt1 WHERE c1='1' AND c2 = '1-2';
cqlsh:test> select * from tt1;
c1 | c2 | cs | c3
----+-----+----+----
1 | 1-1 | s4 | x
1 | 1-3 | s4 | x
1 | 1-4 | s4 | x
(3 rows)
cqlsh:test> delete from tt1 WHERE c1='1' AND c2 = '1-4';
cqlsh:test> select * from tt1;
c1 | c2 | cs | c3
----+-----+----+----
1 | 1-1 | s4 | x
1 | 1-3 | s4 | x
(2 rows)
}}
Same scenario with manual DELETion leads to another result:
{{
cqlsh:test> create table tt1 ( c1 text , c2 text , c3 text, cs text static,
PRIMARY KEY (c1, c2) );
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-1', 'x', 's1');
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-2', 'x', 's2');
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-3', 'x', 's3');
cqlsh:test> insert into tt1 (c1, c2, c3, cs) VALUES ( '1', '1-4', 'x', 's4');
cqlsh:test> select * from tt1;
c1 | c2 | cs | c3
----+-----+----+----
1 | 1-1 | s4 | x
1 | 1-2 | s4 | x
1 | 1-3 | s4 | x
1 | 1-4 | s4 | x
(4 rows)
cqlsh:test> delete from tt1 WHERE c1='1' AND c2 = '1-2';
cqlsh:test> select * from tt1;
c1 | c2 | cs | c3
----+-----+----+----
1 | 1-1 | s4 | x
1 | 1-3 | s4 | x
1 | 1-4 | s4 | x
(3 rows)
cqlsh:test> delete from tt1 WHERE c1='1' AND c2 = '1-4';
cqlsh:test> select * from tt1;
c1 | c2 | cs | c3
----+-----+----+----
1 | 1-1 | s4 | x
1 | 1-3 | s4 | x
(2 rows)
}}
Is this behavior bug or it's declared somewhere? Is it really good that
deletion behavior is inconsistent?
