Abstract
There are provided a system and a computer program product for operating multi-node data stores. The system stores a data table in a first computing node and stores an index table 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. The system performs operations that update or read the data table accessed from the first computing node and the index table accessed from the second computing node. The operations optimizes 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.
