Abstract: The described methods, systems, and other aspects can, by way of example, advantageously provide efficient metadata storage in a master-slave node-based metadata store of a distributed storage system. An example method may write a first transaction entry in a transaction log of a first node based on a first request for a first operation associated with a first storage object. The method may then request a second node write the first transaction entry in a transaction log of the second node based on the first request. While awaiting a first acknowledgment of a completion of a writing of the first transaction entry in the transaction log of the second node, the method may proceed to write one or more subsequent transaction entries in the transaction log of the first node based on one or more subsequent requests for one or more operations associated with one or more storage objects.
