Methods and systems of operating a database management system dmbs in a strong consistency mode

A computerized system useful for operating a database management system DMBS in a strong consistency mode comprising:

• at least one processor configured to execute instructions;
• at least one memory containing instructions when executed on the at least one processor, causes the at least one processor to perform operations that:
• implement an atomic transfer of a master node of the DMBS;
• implement a master node restriction, wherein the master node restriction guarantees no more than one master node is ever available, and wherein information about a set of nodes participating in a cluster of the set node of the DMBS is maintained to allow a subset of nodes to determine that the one master node is a master of a subset of data stored in the cluster;
• implement a hybrid clock in the DBMS;
• implement a replication integrity policy, wherein the replication integrity policy guarantees a strict consistency between the set of nodes and maintains replication integrity using a redo mechanism to ensure that no read operations or write operations are allowed when replicas are in an unknown state;
• implement a client intelligence operation, wherein the client intelligence function ensures that each read operation and write operation remains linearizable, and wherein a client participates by tracking each partition state from the cluster;
• and
• combine an atomic transfer of a master node, a master restriction information, a hybrid clock, a replication integrity, and a client intelligence such that all read operations and write operations to the database are linearized.
