JdbcStreamingActionContext

Whether the stream has been cancelled by the Subscriber

The current JDBC Connection

Indicate that the specified number of elements has been delivered. Returns the remaining demand. This is an atomic operation. It must only be called from the synchronous action context which performs the streaming.

Get the current demand that has not yet been marked as delivered and mark it as being in the current batch. When this value is negative, the initial streaming action is still running and the real demand can be computed by subtracting Long.MinValue from the returned value.

Emit a single result of the stream. Any Exception thrown by this method should be passed on to the caller.

Check if the session is pinned. May only be called from a synchronous action context.

Pin the current session. Multiple calls to pin may be nested. The same number of calls to unpin is required in order to mark the session as not pinned anymore. A pinned session will not be released at the end of a primitive database action. Instead, the same pinned session is passed to all subsequent actions until it is unpinned. Note that pinning does not force an actual database connection to be opened. This still happens on demand. May only be called from a synchronous action context.

Restart a suspended streaming action. Must only be called from the Subscriber context.

Finish the stream with onComplete if it is not finished yet. May only be called from a synchronous action context.

Finish the stream with onError if it is not finished yet. May only be called from a synchronous action context.

Unpin this session once. May only be called from a synchronous action context.

The Promise to complete when streaming has finished.
