Note that flush() must be called after the last call to compress() If the data size is large than the max_sync_chunk_size, the compression will be done in the executor. Otherwise, the compression will be done in the event loop. **WARNING: This method is NOT cancellation-safe when used with flush().** If this operation is cancelled, the compressor state may be corrupted. The connection MUST be closed after cancellation to avoid data corruption in subsequent compress operations. For cancellation-safe compression (e.g., WebSocket), the caller MUST wrap compress() + flush() + send operations in a shield and lock to ensure atomicity.
