Carl Steinbach updated HIVE-1815: --------------------------------- Component/s: (was: Drivers) JDBC > The class HiveResultSet should implement batch fetching. > -------------------------------------------------------- > > Key: HIVE-1815 > URL: https://issues.apache.org/jira/browse/HIVE-1815 > Project: Hive > Issue Type: Improvement > Components: JDBC > Affects Versions: 0.5.0 > Environment: Custom Java application using the Hive JDBC driver to > connect to a Hive server, execute a Hive query and process the results. > Reporter: Guy le Mar > Fix For: 0.6.0 > > > When using the Hive JDBC driver, you can execute a Hive query and obtain a > HiveResultSet instance that contains the results of the query. > Unfortunately, HiveResultSet can then only fetch a single row of these > results from the Hive server at a time. As a consequence, it's extremely slow > to fetch a resultset of anything other than a trivial size. > It would be nice for the HiveResultSet to be able to fetch N rows from the > server at a time, so that performance is suitable to support applications > that provide human interaction. > (From memory, I think it took me around 20 minutes to fetch 4000 rows.) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
