Lockless Read Servicing with Write Indicators for Data Integrity

The patent extracts the locking mechanism from the data access protocol and replaces it with a lockless approach using version indicators. Read operations no longer require acquiring locks on storage locations,而是 use version numbers to detect write operations. This removes the overhead of lock management while maintaining data coherency through version checking.

The patent introduces version indicators as an intermediary mechanism between read and write operations. Instead of direct lock-based coordination, version numbers serve as mediators that allow read operations to detect write operations without blocking. The version indicator acts as a signaling mechanism that enables concurrent access while maintaining data integrity.

The patent applies preliminary action by pre-incrementing version indicators during write operations before the actual data write completes. This allows read operations to check the version indicator in advance and detect write operations without waiting for lock acquisition. The version check is performed preliminarily, enabling read operations to proceed without blocking latency.

The patent enables read operations to skip the lock acquisition step entirely and rush through to data retrieval by using version indicator checking. Instead of following the traditional path of acquiring locks before reading, the lockless approach allows reads to proceed directly to the storage location and use version numbers to verify data freshness, significantly reducing processing latency.

The patent segments the access conflict management into independent version indicators for each storage location. Instead of using centralized lock management that coordinates all nodes, each storage location has its own version indicator that nodes can check independently. This segmentation allows multi-node active/active operation without complex inter-node coordination for conflict management.

The patent implements self-service by enabling each node to independently manage its own read operations using local version indicator checks. Nodes do not need to coordinate with other nodes through lock protocols; instead, each node services its own read requests by checking version indicators at storage locations, simplifying access conflict management in multi-node configurations.
