EN We propose an algorithm, called Lorq, for managing NoSQL data replication. Lorq is based on consensus quorum approach and is focused on replicating logs storing update operations. Read operations can be performed on different levels of consistency (from strong to eventual consistency), realizing so-called service level agreements (SLA). In this way the trade-off among availability/latency, partition tolerance and consistency is considered. We discuss correctness of Lorq and its importance in developing modern information systems based on geo-replication and cloud computing.
