> Key: CASSANDRA-18967
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18967
> Project: Cassandra
> Issue Type: Bug
> Components: Accord
> Reporter: Luis E Fernandez
> Priority: Normal
> Fix For: 5.x

> *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}
