  • Quorum-based replication of data records
    Patent number: 10366106
    Abstract: Disclosed herein are system, method, and computer program product embodiments for quorum-based replication of data records. In one embodiment, a read request for reading a record is received from a user node on a replica node of a cluster of replica nodes. The record is then determined not committed on the replica node. In response to the determination, an update message indicative of whether the number of replica nodes on which the record is durable exceeds a threshold is received on the replica node. In response to the number of replica nodes exceeds the threshold, a value of the record on the replica node is transmitted to the user node.

  • Handling large writes to distributed logs
    Patent number: 10360145
    Abstract: A system includes writing of log data in chunks over a first range of heap log sequence positions of a heap log stored in the non-volatile memory system, and writing of a heap anchor marker in a first anchor stream of a transaction log stored in the non-volatile memory system, at a first transaction log sequence position of the transaction log, wherein the first anchor stream is associated with a first stream of the transaction log, and the heap anchor marker identifies the first range of heap log sequence positions of the heap log.
