1. What is the issue? Please be detailed.
I am preparing a face-to-face survey with 1,000 completed interviews, average length 20 minutes, using background-audio at quality=voice-only. We will also submit partial interviews and refusals, where only two or three questions are answered but a short recording still exists(the number of these interviews will be a lot more even though most of them will be pretty short. The form additionally uses an audit row with track-changes=true and location tracking enabled, and one begin repeat group for the household roster.
My questions are about getting that data off the server efficiently and about whether this volume causes problems anywhere in the pipeline.
Specifically:
- What is the fastest and most reliable way to download everything, submissions plus attachments, at this volume? Is the browser "Download all data and attachments" zip dependable at this size, or is there any other way to download the data faster and frequently for quality control?
- Is it better to download incrementally during fieldwork rather than once at the end? If so, is there a recommended pattern for pulling only new submissions?
- Are there performance concerns on the Central server itself from ~1,000+ submissions that each carry an audio file, an audit log and a repeat group?
- Does having both an audit log and a repeat group noticeably slow the CSV export, since the repeat produces its own file?
- Anything to watch on the device and upload side?
