cache_level as BLOCK and few loads with latest store which contain the BLOCKLET
information and have cache_level BLOCKLET. For these type of scenarios we need
to have separate task and footer schemas. For all loads with/without blocklet
info there will not be any additional cost of maintaining 2 variables
