HI Michal;
The consistency level defaults to ONE for all write and read operations.
However consistency level is also set for the keyspace.
Could it be possible that your queries are spanning multiple keyspaces which
bear different levels of consistency ?

Hi,
We're using C* 2.1.2, django-cassandra-engine which in turn uses cqlengine.
LOCAL_QUROUM is set as default consistency level. From time to time we get
timeouts while talking to the database but what is strange returned consistency
level is not LOCAL_QUROUM:
code=1200 [Coordinator node timed out waiting for replica nodes' responses]
message="Operation timed out - received only 3 responses."
info={'received_responses': 3, 'required_responses': 4, 'consistency': 'ALL'}
code=1200 [Coordinator node timed out waiting for replica nodes' responses]
message="Operation timed out - received only 1 responses."
info={'received_responses': 1, 'required_responses': 2, 'consistency':
'LOCAL_QUORUM'}
code=1100 [Coordinator node timed out waiting for replica nodes' responses]
message="Operation timed out - received only 0 responses."
info={'received_responses': 0, 'required_responses': 1, 'consistency': 'ONE'}
Any idea why it might happen?
