Abstract
There is provided a method for operating multi-node data stores. A data table is stored in a first computing node and an index table is stored in a second computing node. The index table provides keys used for accessing data in the first computing node and other multi-node data stores. Operations that update or read the data table accessed from the first computing node and the index table accessed from the second computing node are performed. The operations optimize between latency in updating or reading the data table and the index table and data consistency maintained between data entries in the data table and data entries pointed by indices in the index table.
