-Applying QualifierFilter to one column family only.
David Koch 2012-07-18, 22:06
When scanning a table with 2 column families, is it possible to apply
a QualifierFilter selectively to one family but still include the other
family in the scan?
The layout of my table is as follows:
<rowkey> T:<timestamp> --> <data>, S:<summary_item> --> <value>
For each <rowkey> family T contains timestamp/data key/value pairs. Column
S contains summary information about this row key.
I want to apply a QualifierFilter to column T only - i.e filter by
<timestamp> but return also all of S whenever the set of key/values matched
in T is not empty. Is this doable using standard HBase filters? If so, how?
If not could I implement such a filter myself using FilterBase?
