MapReduce has been facing some criticism based on some recent performance tests. Don’t worry. The outcome is basically not to compete with DBMS in areas where DBMS is already good. The article suggests MapReduce should be used to solve the following problem types:

  • text tokenization, indexing, and search
  • Creation of other kinds of data structures (e.g., graphs)
  • Data mining and machine learning
  • Data transformation
