Cloudera's Impala open source project is now a public beta. The company also launches a real-time query services as its second subscription offering. This is a big week in the analytics world as both Gartner's Data & Analytics Summit in Grapevine, TX and the Strata Data Conference in San Jose are taking place. Many vendors are attending and exhibiting at both; some vendors are only at one, but just about everyone in the analytics world is exhibiting at one of them, at least. Strata, which kicks off today, is more of an announcement vehicle for vendors though, and today three big names in the Big Data world -- Cloudera, MapR and AtScale -- have new releases to announce.
