Lars Hofhansl commented on HBASE-9000:
--------------------------------------
Is that an FB issue only?
In current HBase (0.94+) I see:
{code}
kvsetIt = kvsetAtCreation.tailSet(getHighest(key, kvsetItRow)).iterator();
snapshotIt = snapshotAtCreation.tailSet(getHighest(key,
snapshotItRow)).iterator();
{code}
In reseek.
> Linear reseek in Memstore

> Key: HBASE-9000
> URL: https://issues.apache.org/jira/browse/HBASE-9000
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.89-fb
> Reporter: Shane Hogan
> Priority: Minor
> Fix For: 0.89-fb
>
>
> This is to address the linear reseek in MemStoreScanner. Currently reseek
> iterates over the kvset and the snapshot linearly by just calling next
> repeatedly. The new solution is to do this linear seek up to a configurable
> maximum amount of times then if the seek is not yet complete fall back to
> logarithmic seek.
