> Key: HBASE-5010
> URL: https://issues.apache.org/jira/browse/HBASE-5010
> Project: HBase
> Issue Type: Bug
> Reporter: Mikhail Bautin

> In ScanWildcardColumnTracker we have
> {code:java}
>
> this.oldestStamp = EnvironmentEdgeManager.currentTimeMillis() - ttl;
> ...
> private boolean isExpired(long timestamp) {
> return timestamp < oldestStamp;
> }
> {code}
> 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.
