Nick Dimiduk updated HBASE-9283: -------------------------------- Affects Version/s: 0.95.2 > Struct and StructIterator should properly handle trailing nulls > --------------------------------------------------------------- > > Key: HBASE-9283 > URL: https://issues.apache.org/jira/browse/HBASE-9283 > Project: HBase > Issue Type: Bug > Affects Versions: 0.95.2 > Reporter: Nick Dimiduk > > For a composite row key, Phoenix strips off trailing null columns values in > the row key. The reason this is important is that then new nullable row key > columns can be added to a schema without requiring any data upgrade to > existing rows. Otherwise, adding new row key columns to the end of a schema > becomes extremely cumbersome, as you'd need to delete all existing rows and > add them back with a row key that includes a null value. > Rather than Phoenix needing to modify the iteration code everywhere (as > [~ndimiduk] outlined here: > https://issues.apache.org/jira/browse/HBASE-8693?focusedCommentId=13744499&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13744499), > it'd be better if StructIterator handled this out-of-the-box. Otherwise, if > Phoenix has to specialize this, we'd lose the interop piece which is the > justification for switching our type system to this new one in the first > place. -- This message is automatically generated by JIRA.
