Tyler Hobbs created CASSANDRA-10796:
---------------------------------------
Summary: Views do not handle single-column deletions of view PK
columns correctly
Key: CASSANDRA-10796
URL: https://issues.apache.org/jira/browse/CASSANDRA-10796
Project: Cassandra
Issue Type: Bug
Components: Coordination
Reporter: Tyler Hobbs
Assignee: Tyler Hobbs
Fix For: 3.0.1, 3.1
When a materialized view has a regular base column in its primary key, and that
regular base column is deleted through a single-column deletion, the view does
not handle it correctly, and may produce an error.
For example, with a table like:
{noformat}
CREATE TABLE foo (
a int, b int, c int, d int
PRIMARY KEY (a, b)
)
{noformat}
and a view like:
{noformat}
CREATE MATERIALIZED VIEW BAR
AS SELECT * FROM foo
WHERE ...
PRIMARY KEY (a, d, b)
{noformat}
a deletion like this will not be handled correctly:
{noformat}
DELETE d FROM foo WHERE a = 0 AND b = 0
{noformat}
The source of the problem is that we aren't checking whether individual cells
in the TemporalRow are live or not when building the clustering and partition
key for the row. Instead, we're just using the cell value, which is an empty
ByteBuffer.
I should have a patch with a fix and tests posted tomorrow.
