Method and apparatus for maintaining replica sets

A system for performing asynchronous replication in a distributed database environment comprising a plurality of nodes, the system comprising:

• at least one processor operatively connected to a memory, the at least one processor when running is configured to execute a plurality of system components, wherein the plurality of system components comprise:
• a role component configured to establish a role associated with a plurality of nodes, wherein the role component is configured to establish a primary node with a primary role and at least a plurality of secondary nodes with a secondary role;
• an execution component configured to restrict write requests received from client computer systems to the primary node;
• a replication component configured to:
• asynchronously replicate write operations performed on the primary node to the plurality of secondary nodes such that all write operations are executed at least under a default consistency model for data replication in a database, wherein the default consistency model comprises an eventual consistency mode;
• identify that at least one write operation includes a user requirement such that the at least one write operation is executed with additional requirements over the default consistency model;
• record replication status that reflects that the at least one write operation has occurred for the at least one write from the plurality of secondary nodes;
• and
• confirm the at least one write operation responsive to determining that that at least one write operation has been replicated to a threshold number of the plurality of secondary nodes.
