multiget_slice does not return correct columns based on column slice
--------------------------------------------------------------------
Key: CASSANDRA-1861
URL: https://issues.apache.org/jira/browse/CASSANDRA-1861
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.7.0 rc 2
Reporter: chirag patel
Priority: Critical
We are using Random Partitioner.
We are trying to do a multiget_slice on a column family which is sorted by
UTF8Type and it does not behave as expected.
ColumnFamily: RecordIndexes
Columns sorted by: org.apache.cassandra.db.marshal.UTF8Type
Row cache size / save period: 0.0/0
Key cache size / save period: 200000.0/3600
Memtable thresholds: 0.29062499999999997/62/60
GC grace seconds: 864000
Compaction min/max thresholds: 4/32
Read repair chance: 1.0
So RECORDINDEXES CF has 1 key with 3 columns as shown below.
In [6]: RECORDINDEXES.get('testkey')
Out[6]: {u'A_1.2.3.4_1': '1', u'N_edited.test.com_1': '1', u'P_45653_1': '1'}
When I do a multiget_slice with column_start as "N_edi.test.com._" and finish
column as 'P_', I should not get any thing as there is no column starting with
"N_edi.test.com._" as column name, but I do get one column back which is
incorrect.
***********************************
In [11]: RECORDINDEXES.get('testkey',
column_start='N_edi.test.com._',column_finish='P_')
Out[11]: {u'N_edited.test.com_1': '1'}
***********************************
Some more invalid results
***********************************
In [9]: RECORDINDEXES.get('testkey', column_start='NS_',column_finish='P_')
Out[9]: {u'N_edited.test.com_1': '1'}
In [10]:
In [16]: RECORDINDEXES.get('testkey', column_start='NS',column_finish='P_')
Out[16]: {u'N_edited.test.com_1': '1'}
In [17]:
***********************************
I tried this with hector client library as well, so its the same result.
Can anybody please look into this?
This is blocking issue for us as our data retrieval heavily depends on
multiget_slice query.
FYI: beta3 release also had this problem, so we upgraded to rc2 and still
seeing the same problem.
Thanks,
