Cloudera Open Source Impala Brings Real Time Queries to Hadoop
Page 1 of 1
Cloudera, one of the leading commercial sponsors of Hadoop, is now aiming to enable faster Big Data queries by introducing a new technology codenamed Impala. The goal with Impala is to enable rapid and interactive queries.
Cloudera CEO Mike Olson said MapReduce was originally designed by consumer Internet companies to process large-scale, batch data workloads.
"If you want to get at your data for interactive queries, you just can't get there with MapReduce," he said. "That means that Hadoop just doesn't get deployed for a whole bunch of workloads."
How to Speed up Hadoop
Impala doesn't replace MapReduce, Olson noted. "What we have done is added another execution framework – another way to get at the identical data in a Hadoop cluster. Customers can transform and analyze data with MapReduce and they can query the results using Impala."
