Latest Patents

Sukhdeep's latest patents include an "Action framework in software transactional memory." This patent describes a software transactional memory system that implements a lightweight key-based action framework. The framework features a set of unified application programming interfaces (APIs) provided by an STM library, allowing clients to implement actions that can be registered, queried, and updated using specific keys by transactions or transaction nests in STM code. Each action comprises a key, state information, and a set of callbacks that can be linked to the validation, commit, abort, and/or re-execution phases of transaction execution. These actions enhance the built-in concurrency controls of the STM system with customized control logics, support transaction nesting semantics, and facilitate integration with garbage collection systems.

Another notable patent is for "Systems and methods for asynchronous schema changes." This disclosure outlines systems and methods for updating database servers with schema changes to prevent concurrency anomalies. The system can receive a snapshot of a table to be updated with a new schema, taken at a specific time. It reads each row from the snapshot and compares it to the rows in the table at a later time. Based on this comparison, the system identifies the rows from the snapshot that have not changed and writes them to the table being updated.
