Zoltan Haindrich commented on HIVE-20513:
-----------------------------------------
I will rename those methods in the next patch....but the following seems to be
right now:
{code}
public long computeOnlineDataSizeFast3(Statistics statistics) {
return computeOnlineDataSizeGeneric(statistics,
5 + 4, // list header ; value length stored as vint
8 // maintenance structure consists of 1 long
);
}
{code}
