--------------------------------------------
Summary: Aggregation (SUM) in a transaction block fails
Key: CASSANDRA-18967
URL: https://issues.apache.org/jira/browse/CASSANDRA-18967
Project: Cassandra
Issue Type: Bug
Reporter: Luis E Fernandez
*System configuration and information:*
Single node Cassandra with Accord transactions enabled running on docker
Built from commit:
[a7cd114435704b988c81f47ef53d0bfd6441f38b|https://github.com/apache/cassandra/commit/a7cd114435704b988c81f47ef53d0bfd6441f38b]
CQLSH: [cqlsh 6.2.0 | Cassandra 5.0-alpha2-SNAPSHOT | CQL spec 3.4.7 | Native
protocol v5]
*Steps to reproduce in CQLSH:*
{code:java}
CREATE KEYSPACE accord WITH replication = {'class': 'SimpleStrategy',
'replication_factor': '1'} AND durable_writes = true;{code}
{code:java}
CREATE TABLE accord.accounts (
partition text,
account_id int,
balance int,
PRIMARY KEY (partition_key, account_id)
) WITH CLUSTERING ORDER BY (account_id ASC)
{code}
{code:java}
BEGIN TRANSACTION
INSERT INTO accord.accounts (partition, account_id, balance) VALUES
('default', 0, 100);
INSERT INTO accord.accounts (partition, account_id, balance) VALUES
('default', 1, 100);
COMMIT TRANSACTION;{code}
bug happens after executing the following statement:
I expect the result to be a single row consisting of the sum of all the
balances (100 + 100 = 200).
{code:java}
BEGIN TRANSACTION
SELECT SUM(balance)
FROM accord.accounts
WHERE
partition = 'default'
AND account_id IN (0, 1);
COMMIT TRANSACTION;{code}
Bug / Error:
======================================================================
The return result includes all the rows with no sum.
{code:java}
system.sum(balance)
----------------
100
100{code}
Note that executing the same statement without the transaction returns the
expected result:
{code:java}
system.sum(balance)
----------------
200{code}
{color:#172b4d}This is found while testing Accord transactions with
[~henrik.ingo] and team.{color}
