Abstract: Distributed database systems including compute nodes and page servers are described herein that enable separating logical and physical storage of database files in a distributed database system. A distributed database system includes a page server and a compute node and is configured to store a logical database file that includes data and is associated with a file identifier. Each page server is configurable to store slices (i.e., subportions) of the logical database file. The compute node is coupled to the plurality of page servers and configured to store the logical database file responsive to a received command. In an aspect, such storage may comprise slicing the data comprising the logical database file into a set of slices with each being associated with a respective page server, maintaining an endpoint mapping for each slice of the first set of slices, and transmitting each slice to the associated for storage thereby.

Abstract: Assembly of a state of user data as of a particular point in time in the context of the data being spread across multiple storage segment servers. Furthermore, the assembly occurs despite the storage segment servers not needing to coordinate a timing of any snapshots. Rather, the storage segment servers perform a snapshot of the portion of the data that it individually stores without having to coordinate with any other storage segment server. The particular point of time may be any arbitrary time, such as a time selected by a user.
