Subject: HBase Negation or NOT operator
Does HBase not support an SQL NOT operator on complex filters? I would like
to filter out whatever matches a complex nested filter.
my use case is to parse a query like this(below) and build a HBase filter
(field1=value1 AND NOT ((field2=value2 OR field3=value3) AND field4=value4))
How to go about this , any ideas? What will be a better approach -
implement a custom filter that excludes a row qualified by another filter
or to convert input query into an opposite query.
