Jeremy Hanna updated CASSANDRA-7537:
------------------------------------
Labels: LWT (was: )
> Updates and partition tombstones are not given the same timestamp in a CAS
> batch
> --------------------------------------------------------------------------------
>
> Key: CASSANDRA-7537
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7537
> Project: Cassandra
> Issue Type: Bug
> Reporter: Nicolas Favre-Felix
> Priority: Major
> Labels: LWT
>
> Create a table with one partition and 2 CQL rows:
> {code}
> CREATE TABLE t1 (
> k text,
> c text,
> v text,
> PRIMARY KEY(k,c)
> );
> BEGIN BATCH
> INSERT INTO t1 (k,c,v) VALUES ('x','1','1');
> INSERT INTO t1 (k,c,v) VALUES ('x','2','2');
> APPLY BATCH;
> {code}
> CAS-delete the full partition based on the expected value of a single column:
> {code}
> cqlsh:ks1> SELECT * FROM t1 WHERE k='x';
> k | c | v
> ---+---+---
> x | 1 | 1
> x | 2 | 2
> (2 rows)
> cqlsh:ks1> BEGIN BATCH
> ... UPDATE t1 SET v = '0' WHERE k = 'x' AND c = '1' IF v = '1';
> ... DELETE FROM t1 WHERE k = 'x';
> ... APPLY BATCH;
> [applied]
> -----------
> True
> cqlsh:ks1> SELECT * FROM t1 WHERE k='x';
> k | c | v
> ---+---+---
> x | 1 | 0
> (1 rows)
> {code}
> sstable2json reports that the updated column has a timestamp 1 greater than
> the partition delete:
> {code}
> {"key": "78","metadata": {"deletionInfo":
> {"markedForDeleteAt":1405097039224999,"localDeletionTime":1405097039}},"columns":
> [["1:v","0",1405097039225000]]}
> {code}
> All mutations in a CAS batch should be applied with the same timestamp.
