Hello folks, I saw a lot of questions about SingleColumnValueFilter but I have one more. The question is about setFilterIfMissing value and it's behaviour with other column families. I have the following in my db: hbase(main):004:0> scan 'c59d09d425244b9bb216a229c2441819_resource' ROW COLUMN+CELL
resource-id column=f:project_id, timestamp=1397138905401, value="project-id" resource-id column=f:s_test-1, timestamp=1397138905401, value="1" resource-id column=m:9222030811254775807+test-1+instance!cumulative!, timestamp=1397138905401, value={"$date": 1341225600000} resource-id column=m:9222030811314775807+test-1+instance!cumulative!, timestamp=1397138905377, value={"$date": 1341225540000} resource-id-2 column=f:project_id, timestamp=1397138905422, value="project-id-2" resource-id-2 column=f:s_test, timestamp=1397138905422, value="1" resource-id-2 column=m:9222030811134775807+test+instance!cumulative!, timestamp=1397138905422, value={"$date": 1341225720000} After filter applying I see the following: hbase(main):005:0> scan 'c59d09d425244b9bb216a229c2441819_resource', {FILTER => "(SingleColumnValueFilter ('f', 's_test-1', =, 'binary:\"1\"', true, false))"} ROW COLUMN+CELL resource-id column=f:project_id, timestamp=1397138905401, value="project-id" resource-id column=f:s_test-1, timestamp=1397138905401, value="1" resource-id column=m:9222030811254775807+test-1+instance!cumulative!, timestamp=1397138905401, value={"$date": 1341225600000} resource-id column=m:9222030811314775807+test-1+instance!cumulative!, timestamp=1397138905377, value={"$date": 1341225540000} resource-id-2 column=m:9222030811134775807+test+instance!cumulative!, timestamp=1397138905422, value={"$date": 1341225720000} I wonder why I see resource-id-2 in output even with setFilterIfMissing==True? Row with id 'resource-id-2' doesn't contain "f:s_test-1", it contains only "f:s_test". From docs about setFilterIfMissing: "If true, the entire row will be skipped if the column is not found." So column 's_test-1' is not found in resource-id-2. But I still see this row (but only 'm' CF) in output. Of course I can determine COLUMNS=['f'] and resource-id-2 will not be shown. But I can't because I need values from 'm'. Could you please comment this behaviour? Thanks, Nadya (From OpenStack Ceilometer team)
