System and method for providing high availability data

A computer-implemented method comprising:

• obtaining a data set;
• writing a first plurality of copies of the data set at a first plurality of hosts within a first subset of a plurality of data centers;
• reading a second plurality of copies of the data set at a second plurality of hosts within a second subset of the plurality of data centers;
• evaluating causal relationships between elements of the second plurality of copies of the data set, wherein evaluating causal relationships comprises at least determining causal relationships between elements in the second plurality of copies of the data set that are not causal ancestors of other elements in the second plurality of copies of the data set;
• reconciling between at least two copies of the second plurality of copies, wherein the at least two copies comprise respective elements that are determined not to be causal ancestors of one another;
• and
• determining a single copy of the data set from the second plurality of copies of the data set based, at least in part, on the reconciling between the at least two copies.

A computer-readable medium containing computer-executable instructions, wherein the computer-executable instructions, when executed by a processor, cause the processor to:

• read a plurality of copies of a data set at a plurality of hosts within a subset of a plurality of data centers;
• evaluate causal relationships between elements of the plurality of copies of the data set, wherein evaluating causal relationships comprises at least evaluating causal relationships between elements in the second plurality of copies of the data set that are not causal ancestors of other elements in the plurality of copies of the data set;
• and
• determine a single copy of the data set from the plurality of copies of the data set based on the evaluated causal relationships between the elements of the plurality of copies of the data set.
