This could be done in the PTableImpl.newKey method. > 5. for a key value column with a default value, we can get away without > incurring any storage cost. Although a little bit of extra effort than if we > persisted the default value on an UPSERT for key value columns, this approach > has the benefit of not incurring any storage cost for a default value. > * serialize any default value into KeyValueColumnExpression > * in the evaluate method of KeyValueColumnExpression, conditionally use > the default value if the column value is not present. If doing partial > evaluation, you should not yet return the default value, as we may not have > encountered the the KeyValue for the column yet (since a filter evaluates > each time it sees each KeyValue, and there may be more than one KeyValue > referenced in the expression). Partial evaluation is determined by calling > Tuple.isImmutable(), where false means it is NOT doing partial evaluation, > while true means it is. > * modify EvaluateOnCompletionVisitor by adding a visitor method for > RowKeyColumnExpression and KeyValueColumnExpression to set > evaluateOnCompletion to true if they have a default value specified. This > will cause filter evaluation to execute one final time after all KeyValues > for a row have been seen, since it's at this time we know we should use the > default value. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
