Filter HFiles based on TTL -------------------------- Key: HBASE-5010 URL: https://issues.apache.org/jira/browse/HBASE-5010 Project: HBase Issue Type: Bug Reporter: Mikhail Bautin Assignee: Mikhail Bautin
In ScanWildcardColumnTracker we have { this.oldestStamp = EnvironmentEdgeManager.currentTimeMillis() - ttl; ... private boolean isExpired(long timestamp) { return timestamp < oldestStamp; } } but this time range filtering does not participate in HFile selection. In one real case this caused next() calls to time out because all KVs in a table got expired, but next() had to iterate over the whole table to find that out. We should be able to filter out those HFiles right away. I think a reasonable approach is to add a "default timerange filter" to every scan for a CF with a finite TTL and utilize existing filtering in StoreFile.Reader.passesTimerangeFilter. -- This message is automatically generated by JIRA.
