On December 17, Teradata announced the finalization of the acquisition of RainStor, a big data archiving company that specializes in archival solutions for Hadoop. The acquisition of RainStor gives Teradata ownership of RainStor’s technology for compressing and freezing Hadoop datastores for archival purposes. RainStor’s archival technology empowers companies to compress and store Hadoop data as Hadoop-based datasets proliferate throughout the enterprise in conjunction with the larger transition to data-driven operational and strategic analytics. The acquisition represents Teradata’s fourth major acquisition this year following upon the purchase of Revelytix, Hadapt and Think Big Analytics. Terms of the acquisition were not disclosed although most of RainStor employees will remain in their pre-acquisition locations in San Francisco and Gloucester. The acquisition strengthens Teradata’s Hadoop solutions by augmenting its ability to provide customers with enterprise-wide data archival capabilities.
