-------------------------------
Summary: Client side scanning prefetching.
Key: HBASE-12338
URL: https://issues.apache.org/jira/browse/HBASE-12338
Project: HBase
Issue Type: Sub-task
Components: Client
Affects Versions: 0.98.6.1, 1.0.0, 2.0.0
Reporter: Yi Deng
Assignee: Yi Deng
Since server side prefetching was not proved to be a good way to prefetch, we
need to do it on client side.
This is a wrapper class that takes any instance of `ResultScanner` as the
underneath scanning component. The class will schedule the scanning in a
background thread. There is a buffering queue storing prefetched results,
whose's length is configurable. The prefetcher will release the thread if the
queue is full and wait for results to be consumed.
