Description

CompactionChecker.chore() is called periodically for compacting. as follow:

//代码占位符
protected void chore() {
    for (Region r : this.instance.onlineRegions.values()) {
        // Skip compaction if region is read only
        if (r == null || r.isReadOnly()) {
            continue;
        }


        HRegion hr = (HRegion) r;
        for (HStore s : hr.stores.values()) {
            // ...
        }
    }
}
