Once we trust that > the N in bucketN for "base" spit is reliable, all delete events not matching N can be skipped. > This is useful to protect against extreme cases where someone runs an update/delete on a partition that matches 10 billion rows thus generates very many delete events. > Since HIVE-19890 all acid data files must have bucketid/writerid in the file name match bucketid/writerid in ROW__ID in the data. > {{OrcRawRecrodMerger.getDeltaFiles()}} should only return files representing the right {{bucket}} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
