摘要： A system is described for providing scalable in-memory caching for a distributed database. The system may include a cache, an interface, a non-volatile memory and a processor. The cache may store a cached copy of data items stored in the non-volatile memory. The interface may communicate with devices and a replication server. The non-volatile memory may store the data items. The processor may receive an update to a data item from a device to be applied to the non-volatile memory. The processor may apply the update to the cache. The processor may generate an acknowledgement indicating that the update was applied to the non-volatile memory and may communicate the acknowledgment to the device. The processor may then communicate the update to a replication server. The processor may apply the update to the non-volatile memory upon receiving an indication that the update was stored by the replication server.
