An Abstract Description Method of Map-Reduce-Merge Using Haskell
Algorithm 17
match ::K21 –Key21 as input data
K22 –Key22 as input data
Bool –Satisfy the merge condition or not
match K21 K22 = let (int, str) = K21 in if str == K22 then True else False
mergeResult ::KV1 –Record1 as input data
KV2 –Record2 as input data
KV3 –Record3 as output data
mergeResult (K21, V31) (K22, V32)= let (int, str)= K21 in (int, V3132)
