- * The {@code QueryThreadContext} class is a thread-local context for storing
common query-related information
- * associated to the current thread.
- *
- * <p>It is used to pass information between different layers of the query
execution stack without changing the
- * method signatures. This is also used to populate the {@link MDC} context
for logging.
- *
- * Use {@link #open(String)} to initialize the empty context. As any other
{@link AutoCloseable} object, it should be
- * used within a try-with-resources block to ensure the context is properly
closed and removed from the thread-local
- * storage.
- *
- * Sometimes it is necessary to copy the state of the {@link
QueryThreadContext} from one thread to another. In this
- * case, use the {@link #createMemento()} method to capture the state of the
{@link QueryThreadContext} in the current
- * thread and then use the {@link #open(Memento)} method to initialize the
context in the target thread with the state
- * captured in the {@link Memento} object. The API may be a bit cumbersome,
but it ensures that the state is always
- * copied between threads in a safe way and makes it impossible to use the
{@link QueryThreadContext} from another
- * thread by mistake.
- *
- * It is guaranteed that all server and broker threads running SSE and MSE
will have this context initialized as soon
- * as the request is received. Ingestion threads that use the query execution
stack will also have this context
- * initialized.
