org.apache.hadoop.hbase.regionserver.Store
A Store holds a column family in a Region. Its a memstore and a set of zero or more StoreFiles, which stretch backwards over time.
There's no reason to consider append-logging at this level; all logging and locking is handled at the HRegion level. Store just provides services to manage sets of StoreFiles. One of the most important of those services is compaction services where files are aggregated once they pass a configurable threshold.
The only thing having to do with logs that Store needs to deal with is the reconstructionLog. This is a segment of an HRegion's log that might NOT be present upon startup. If the param is NULL, there's nothing to do. If the param is non-NULL, we need to process the log to reconstruct a TreeMap that might not have been written to disk before the process died.
It's assumed that after this constructor returns, the reconstructionLog file will be deleted (by whoever has instantiated the Store).
Locking and transactions are handled at a higher level. This API should not be called directly but by an HRegion manager.
