Abstract
A data store may implement variable data replication and quorum-based durability schemes. Write requests may be maintained in complete views of the data or incomplete views of the data at storage nodes in a quorum set in the data store. Write requests may be received at different storage nodes sufficient to establish a write quorum, and stored in the replicas of the data at the storage nodes where they are received. Storage nodes maintaining incomplete views of the data may determine that each of the storage nodes maintaining a complete view of the data in the quorum set stores certain write requests, and in response, may reclaim storage space for those write requests included in the incomplete views of the data in order to store other data at the storage node.
