[feature] retrieve the batch periodically

[dawadam]

I need to fetch the 1 minute data over a large period.
Under nodeJS, the recovery will be done with a large storage in RAM which will be a problem for me.
Is there a way to retrieve the batch periodically?
Or after each download request?
With a callback function or something like this.

for downloading large volumes of data, I'd recommend doing it via CLI interface.

CLI it does not consume a lot of memory, and outputs data directly to disk periodically

OK I understand.
But that's not practical for my use case.
I can't use CLI, I must use it in nodejs programme, for dynamic interaction.

It would suffice to add a sending mecanisme, per uploaded file or per batch of uploaded files and it would work.
For example an event triggered at each new generation of batches of candles or a callback function.
