Post to default queue

Question

I was wondering if somebody has more information on how ArcGIS handles queues of versions posting to sde.default. Is there a limit on how many versions ArcGIS can handle? Will there be a time out? Is there a possibility that some posts won’t go through (with the exception of conflicts of course)?

I tried to check the documentation and was not very lucky. Maybe you have more insight!

Happy mapping,

Barbara

There's probably a two-billion-ish limit on the number of concurrent states, but if you were to attempt it, your server would likely fail from old age before it completed.

Keep in mind that a "version" is a named reference to a state in the state tree, and that you're unlikely to have 2^31-1 versions, because each edit is usually its own state, and there's usually more than one edit in any edit session.

I doubt you'd be so lucky that some posts would succeed in such a situation, since it's a multi-pass process.

If you want to find effective limits, I suggest you conduct a benchmark of sorts, with multiple edits per version, with increments of 500 versions at a time. You should be prepared for this to take an inordinate amount of time, and for it to eventually corrupt your instance, so I wouldn't suggest you do this on a production system.

There is no system-managed queuing mechanism for posting versions (traditional or branch).
