Summary:The disclosed embodiments relate to a computer-implemented method for column-oriented access to data. The method can include inserting data into a data store. The data is randomly or sequentially retrievable from the data store by ordering keys for a table in a key-value store and recursively dividing a key space of said table into tablets that each have a range of possible keys. The tablets each contain partitions for key sub-ranges and each partition contains segments. Further, operations on tablets are distributed on different nodes and operations on partitions or segments are handled by using different threads.
