We present Omid - a low latency transaction processing service that powers web-scale production systems at Yahoo. Omid provides ACID transaction semantics on top of traditional key-value storage; its implementation over Apache HBase is open sourced as part of Apache Incubator. Omid can serve hundreds of thousands of transactions per second on standard mid-range hardware, while incurring minimal impact on the speed of data access in the underlying key-value store. Additionally, as expected from always-on production services, Omid is highly available. Omid is currently being integrated as Apache Phoenix transaction engine. This talk combines several incarnations of Omid. The people that contributed to all/part of the presented material are: Aran Bergman, Edward Bortnikov, Yoni Gottesman, Eshcar Hillel, Igor Katkov, Idit Keidar, Ivan Kelly, Matthieu Morel, Sameer Paranjpye and Francisco Perez-Sorrosal.
