Single node and multiple node datastore architecture in a network routing environment

A system comprising:

• a datastore node in a single networking device, wherein the single networking device is a switch or a router, and wherein the datastore node comprises:
• a datastore stored on the single networking device;
• a publisher executing on the single networking device;
• and
• a subscriber executing on the single networking device;
• and
• an index server in communication with the datastore node;
• wherein the index server updates a list of publishers and subscribers in response to receiving a notification from the subscriber indicating a desire to subscribe to a certain dataset;
• further comprising a plurality of datastore nodes each physically located in the single networking device, and wherein each of the plurality of datastore nodes comprises an independent instance of:
• the datastore, wherein the datastore stores state information;
• the publisher;
• and
• the subscriber;
• wherein the index server is a single instance of the index server configured to register and subscribe interests to certain datasets stored across the plurality of datastore nodes;
• wherein the single instance of the index server manages the plurality of datastore nodes located in the single networking device, and wherein the single instance of the index server is configured to:
• maintain a database index comprising a mapping of datasets in the plurality of datastore nodes;
• and
• maintain the list of publishers and subscribers for each of a plurality of datasets distributed across the plurality of datastore nodes.
