----------------------------------------
Done some count in different read scenarios. Per cell, the call form different
offset/length comes this way
Scan All Columns
----------------------------
|getRowOffset|6|
|getRowLength|9|
|getFamilyOffset|2|
|getFamilyLength|1|
|getQualifierOffset|1|
|getQualifierLength|1|
|getTimestamp|1|
|getTypeByte|2|
|getValueLength|4|
Scan with column select (ExplicitColTracker)
----------------------------------------------------------
|getRowOffset|19|
|getRowLength|40|
|getFamilyOffset|14|
|getFamilyLength|14|
|getQualifierOffset|1|
|getQualifierLength|7|
|getTimestamp|1|

Get case
--------------
|getRowOffset|9|
|getRowLength|37|
