description A system, method and apparatus for storing metadata in a metadata store in a robust and efficient manner including receiving a request from a client to perform a data transaction, updating a key-value pair in a metadata store based on the request, entering the data transaction in a transaction log, replicating the last transaction log entry in at least one other storage node in the metadata store and, in response to a threshold event, migrating a first portion of the transaction log from the a data storage medium to a second data storage medium of each of the plurality of data storage nodes.
