Using the file system, but combining multiple json files into a single file might be an option. - Open ‘current.json’ for append, - write the new json, - check file size, - if it’s over a threshold (say 100MB): - rename file (use UUID or timestamp) Your tooling would have to support that, of course (writing each json in a single line might be needed)
