In the race for interactive SQL in Big Data environments, there are two open source based front-runners, Impala and Hive with the Stinger project. Cloudera recently announced that Impala is up to 69 times faster than Hive 0.12 and can outperform DBMS. Other than raw speed, we take a look at other considerations in choosing a SQL engine for Hadoop and also Tez, an application framework for YARN.
EMC Greenplum has announced Pivotal HD, a new Hadoop distribution including a fully compliant SQL MPP database running on HDFS and being “hundreds of times faster than Hive”.
Hortonworks’ new Stinger initiative joins Apache Drill and Cloudera Impala in competition for the best real-time Hadoop implementation.
