James Taylor commented on PHOENIX-1453:
---------------------------------------
If midEndIndex is 0, then we only track the righthand side in the stats and
never end up using leftByteCount and leftRowCount.
{code}
if (midEndIndex > 0) {
- GuidePostsInfo lguidePosts = new
GuidePostsInfo(byteSize, guidePosts.getGuidePosts().subList(0, midEndIndex));
- tracker.clear();
- tracker.addGuidePost(cfKey, lguidePosts, byteSize,
cell.getTimestamp());
+ GuidePostsInfo lguidePosts = new
GuidePostsInfo(leftByteCount, guidePostsRegionInfo
+ .getGuidePosts().subList(0, midEndIndex),
leftRowCount);
+ tracker.clear();
+ tracker.addGuidePost(cfKey, lguidePosts, leftByteCount,
cell.getTimestamp());
addStats(l.getRegionName(), tracker, cfKey, mutations);
}
{code}

> We currently collect guideposts per equal chunk, but we should also capture
> row counts. Should we have a parallel array with the guideposts that count
> rows per guidepost, or is it enough to have a per region count?
