Adam Holmberg created CASSANDRA-8438:
----------------------------------------
Summary: Nested collections not serialized with respect to native
protocol version
Key: CASSANDRA-8438
URL: https://issues.apache.org/jira/browse/CASSANDRA-8438
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Adam Holmberg
Priority: Minor
It appears that inner collections are not encoding collection element count
correctly for protocol version <=2
{code}
from cassandra.cluster import Cluster
s = Cluster(protocol_version=2).connect()
s.execute("CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy',
'replication_factor': '1'}")
s.execute("CREATE TABLE test.test (k int PRIMARY KEY, v map<int,
frozen<list<int>>>)
s.execute("INSERT INTO test.test (k, v ) VALUES ( 1, {1: [2,3,4]})")
print s.execute("SELECT * FROM test.test")
{code}
The map returned is encoded as follows:
00:01:00:04:00:00:00:01:00:1c:*00:00:00:03*:*00:00:00:04*:00:00:00:02:*00:00:00:04*:00:00:00:03:*00:00:00:04*:00:00:00:04
It appears that the outer collection encoding is as expected, while the inner
list count, and list element sizes are _int_ size, instead of _short_. This
does not manifest as a problem in cqlsh because it uses protocol version 3 by
default, which accepts this encoding.
