Quick notes on Impala

Edit: There is now a follow-up post on Cloudera Impala with substantially more detail.

In my world it’s possible to have a hasty 2-hour conversation, and that’s exactly what I had with Cloudera last week. We touched on hardware and general adoption, but much of the conversation was about Cloudera Impala, announced today. Like Hive, Impala turns Hadoop into a basic analytic RDBMS, with similar SQL/Hadoop integration benefits to those of Hadapt. In particular:

Beyond that:

On the whole, Impala seems less mature or capable than Hadapt. But Impala does have a few countervailing advantages:

    Hive is not good for interactive ( < 20 second ) queries, but it has had columnar storage for quite some time. Also, people who are doing large joins in Hive should learn about the various flavors of map-side joins since they are quite fast as they eliminate the reduction (slow) phase
