The following page has been changed by ZhengShao: http://wiki.apache.org/hadoop/Hive/Roadmap ------------------------------------------------------------------------------ #pragma section-numbers 2 = Roadmap/call to add more features = The following is the list of useful features that are on the Hive Roadmap: - * Multiple Group-By Inserts + * Multiple group-by inserts - <code> - FROM src + * Generate multiple group-by results by scanning the source table only once + * Example: + * FROM src - SELECT src.adid, COUNT(src.userid), COUNT(DISTINCT src.userid) GROUP BY src.adid + * SELECT src.adid, COUNT(src.userid), COUNT(DISTINCT src.userid) GROUP BY src.adid - SELECT src.pageid, COUNT(src.userid), COUNT(DISTINCT src.userid) GROUP BY src.pageid + * SELECT src.pageid, COUNT(src.userid), COUNT(DISTINCT src.userid) GROUP BY src.pageid - </code> + * SerDe refactoring, and DynamicSerDe + * Refactor SerDe library to make sure we can serialize/deserialize and let UDF handle complex objects. + * We will be able to write a Hive Query to write data into a table that uses thrift serialization.
