| 发明名称 | Database replication | ||
| 摘要 | A write request is received at a database server from a client application for writing data to persistent data storage. In response to receiving the write request, the database server selects a set of multiple replication servers. The data is sent from the database server to the selected set of multiple replication servers for writing to the persistent data storage. Confirmation is received at the database server from replication servers in the selected set of multiple replication servers. In response to receiving confirmation from the replication servers in the selected set of multiple replication servers, the database server sends to the client application information indicating success of the write request. | ||

| 主权项 | 1. A method comprising: receiving, at a database server, a write request from a client application for writing data to persistent data storage; in response to receiving the write request, selecting, by the database server, a set of multiple replication servers; sending the data from the database server to the selected set of multiple replication servers for writing to the persistent data storage; receiving, at the database server, confirmation from less than all of the replication servers in the selected set of multiple replication servers; and in response to receiving confirmation from the replication servers in the selected set of multiple replication servers, selecting, by the database server, one or more additional replication servers as replacement for the replication servers from which confirmation is not received; and sending the data from the database server to the additional replication servers. | ||
