Systems often use "atomic renames." A file is written to a temporary name (e.g., temp_file.part ) and only renamed to the final filename when complete. The existence of the final filename acts as the file_is_ready signal. Conclusion

Data is being streamed or written; the file is "locked."

In asynchronous programming and distributed systems, operations involving files (like downloading, uploading, or processing large datasets) rarely happen instantaneously. The file_is_ready flag serves as a synchronization mechanism, signaling to dependent processes that a file is complete, validated, and safe to access.

Producers send a message to a queue (like RabbitMQ) only after the file is successfully written to storage.
