Abstract: A storage system for transactional data storage includes a key/value store comprising a first plurality of rows and a second plurality of rows, each of the first plurality of rows including a first key associated with a respective row of a database and a transaction state associated with the respective row, and each of the second plurality of rows including a second key associated with a respective row of the database and a data version of the respective row. The storage system is configured to provide a transaction state to and receive an updated transaction state from a plurality of different systems, each comprising a database engine to perform transactional database operations on the key/value store.

Abstract: Non-limiting examples of the present disclosure describe implementation of an exemplary synchronization protocol to identify file data for synchronization as well as negotiate how to achieve data transport for synchronization of the file data. In one example, a request for synchronization of data is received from a processing device. In response to receiving the request, a response is generated. The response may comprise: identification of file data for synchronization, instructions for accessing the file data and instructions indicating a data transport protocol to utilize to obtain the file data. The response may be transmitted to the processing device, for example, to enable the processing device to synchronize file data. Other examples are also described.

Abstract: A first server computing device, including a processor configured to receive, from a first application instance, a first access request for a file. The first access request may include a first modification privilege request and a modification privilege sharing request. The processor may determine that the file is not locked for editing and grant the first application instance access to the file with modification privileges indicated by the first modification privilege request and without modification privilege sharing permissions indicated by the modification privilege sharing request. The processor may set the file to be locked for editing. The processor may receive, from a second application instance, a second access request including a second modification privilege request. The processor may determine that the file is locked for editing and deny the second application instance access to the file.

Abstract: A system hosts a file system representing a replica of file systems hosted on a plurality of nodes, each node storing data on a first storage medium. The system stores data on a second storage medium that is slower than the first storage medium. The system stores on the second storage medium a file received from one of the nodes when the file remains un-accessed by the nodes for a predetermined period of time. The first storage medium on the plurality of nodes stores a pointer to the file and not the data content of the file stored on the second storage medium. The system provides the file from the second storage medium to the first storage medium on one of the nodes while providing the plurality of nodes read and write access to the file stored on the second storage medium using the pointer on the first storage medium.

The storage system is configured to provide a transaction state to and receive an updated transaction state from a plurality of different systems, each comprising a database engine to perform transactional database operations on the key/value store.

Abstract: A computing system is configured to be coupled to a remote storage system. The remote storage system comprises a key/value store. The computing system is configured to perform transactions on data stored at the remote storage system. The system includes a database client. The database client includes an interface configured to allow a user to request database operations using the database client. The system further includes a database engine coupled to the database client. The database engine is configured to receive requests for database operations from the database client. The database engine is further configured to obtain and operate on transaction state stored as one or more key/value pairs in the key/value store at the remote storage system from the remote storage system. The database engine is configured to transactionally perform data operations, using the transaction state, on one or more data key/value pairs in the key/value store.
