For such cells we make NoTagsKeyValue which avoid getTagsLength parsing overhead in KeyValue. Still HFileReaderV2 creates KeyValue. > This is a 0.98 issue only. > Also in case of DBE, we can consider the tags length and return KeyValue/NoTagsKeyValue -- This message was sent by Atlassian JIRA (v6.3.4#6332)
