Abstract
Systems and methods for key-value pair management. A method embodiment commences upon receiving data records comprising key-value pairs. The key-value pairs are stored in two locations, (1) in an in-memory data structure in a first storage tier, and (2) in a log file in a second storage tier. At some moment in time, an event causes a flush of the in-memory data structure. The flush operations comprise renaming the log file to refer to it as a uniquely identifiable data file in the second storage tier, and populating an index file in the second storage tier. Requests for a value corresponding to a key is satisfied by using the index file to access the uniquely identifiable data file by byte or word offset to a location in the data file so as to retrieve the value of the corresponding key.
