Switching serialization techniques for handling concurrent write requests to a shared file

A system for managing access to a shared file in a storage from client nodes in a network, comprising:

• a first node in communication with the client nodes;
• a second node in communication with the client nodes,
• wherein the first node performs operations, the operations comprising:
• serializing write requests from client nodes to write to the shared file using a first serialization technique involving use of providing an exclusive token to the client nodes to write to the shared file;
• determining whether to switch to the second node to manage write requests to the shared file based on a pattern of write requests to the shared file;
• notifying the client nodes to direct write requests to the shared file to the second node in response to determining to switch to the second node;
• and
• wherein the second node performs processing write requests to the shared file to serialize writes to the shared file, using a second serialization technique different from the first serialization technique to serialize writes to the shared file, after the client nodes are notified to submit the write requests to the shared file to the second node.

A method for managing access to a shared file in a storage from client nodes in a network, comprising:

• serializing, by a first node, write requests from client nodes to write to the shared file using a first serialization technique involving use of providing an exclusive token to the client nodes to write to the shared file;
• determining, by the first node, whether to switch to a second node to manage write requests to the shared file based on a pattern of write requests to the shared file;
• notifying the client nodes to direct write requests to the shared file to the second node in response to determining to switch to the second node;
• and
• processing, by the second node, write requests to the shared file to serialize writes to the shared file, using a second serialization technique different from the first serialization technique to serialize writes to the shared file, after the client nodes are notified to submit the write requests to the shared file to the second node.
