| description | According to some aspects, a database system comprising a processor configured to execute a plurality of system components is provided. The plurality of system components may include an interface component configured to receive a write commit command and provide a write commit confirmation, a snapshot component configured to generate a plurality of snapshots of data stored in a data storage node of a plurality of data storage nodes and identify a committed snapshot representative of data that has been replicated on a majority of the plurality of data storage nodes, and a command processing component configured to modify a data element based on the write commit command, determine whether the majority of the plurality of storage nodes have replicated the modification using the committed snapshot, and generate the write commit confirmation responsive to a determination that the majority of the plurality of data storage nodes have replicated the modification. |
