* Add optimistic concurrency * add optimistic concurrency * fix test * nit * fix tests for sql * fix tests for sql * rebase fix * add one more check * Implement GetLatestAndPredecessor method in datastore and add corresponding tests. This new functionality retrieves the latest resource version and its immediate predecessor, handling cases for single and non-existent resources. Update WriteEvent to utilize this method for improved optimistic concurrency control. * Enhance optimistic concurrency control in WriteEvent method. Added checks for concurrent create operations to ensure only one succeeds, preventing race conditions. Updated tests to validate this behavior with multiple concurrent create attempts. * lint * Refactor optimistic concurrency check in WriteEvent method. Simplified the logic by removing unnecessary condition for single version existence, ensuring more robust handling of concurrent modifications.
