-----------------------------------------
Summary: SELECT count within a partition does not respect LIMIT
Key: CASSANDRA-10380
URL: https://issues.apache.org/jira/browse/CASSANDRA-10380
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Adam Holmberg
Priority: Minor
{code}
cassandra@cqlsh> create KEYSPACE test WITH replication = {'class':
'SimpleStrategy', 'replication_factor': '1'};
cassandra@cqlsh> use test;
cassandra@cqlsh:test> create table t (k int, c int, v int, primary key (k, c));
cassandra@cqlsh:test> INSERT INTO t (k, c, v) VALUES (0, 0, 0);
cassandra@cqlsh:test> INSERT INTO t (k, c, v) VALUES (0, 1, 0);
cassandra@cqlsh:test> INSERT INTO t (k, c, v) VALUES (0, 2, 0);
cassandra@cqlsh:test> select * from t where k = 0;
k | c | v
---+---+---
0 | 0 | 0
0 | 1 | 0
0 | 2 | 0
(3 rows)
cassandra@cqlsh:test> select count(*) from t where k = 0 limit 2;
count
-------
3
(1 rows)
{code}
Expected: count should return 2, according to limit.
Actual: count of all rows in partition
This manifests in 3.0, does not appear in 2.2
