1,what's the relation ship between these term? carbondata file ,block, blocklet ,carbondata file footer ? once we have a batch job to load data into a carbondata table, does that mean the table file will be composed by different blocks ,and each block is a carbondata file which is composed by many blocklets ,and one FileFooter according to the carbondata file format ?
2, how does the column data store as inverted index? invert the dim column data to what ? how does inverted index affect a query ? 3. does all the blocklets store sequence according to the sorted mdk key ? hope someone can give a detail answer.
