Representative embodiments disclose a consistent, low latency, reliable storage system that uses quorum logic. An odd number of storage nodes are selected to store data for a client application. The odd number allows a quorum to be determined. When data is written to the storage nodes, success is identified if the data is successfully written to a majority of the storage nodes. Similarly, when a read is performed, success is identified if the majority of the storage nodes return the same value written in the same write operation. This is determined by matching a value and a version number for each node. Additional data is written to the storage nodes along with the values to allow the system to identify and repair inconsistencies in the data. In some embodiments, both the current data and prior data are stored to aid in repairing inconsistent data.

Quorum based reliable low latency storage

Determining compatibility of data structures. A method may be practiced in a computing environment. The method includes accessing a first type defined in a mark-up object. The first type includes a first structure including a first plurality of fields. A second type defined in a mark-up object is accessed. The second type includes a second structure including a second plurality of fields. The first structure and the second structure are compared. Based on the comparison, a determination is made that the first type is compatible with the second type.
