Sort server-side in SavedObject export #55128

tylersmalley · 2020-01-16T21:57:55Z

Sorting/Aggregating by _id was removed in #52517

I am not seeing a reason yet as to why the sorting here is necessary as we never perform additional fetches of the data outside of exportSizeLimit which would require consistent sorting.

I've asked Mike Cote to take a look as well, but my guess is this was only added to produce stable exports.

mikecote · 2020-01-17T12:48:27Z

The sort by _id was there to solve this issue #29747. Though for now since we're loading them all at the same time, we could just do so on the server side or drop the this feature overall.

rudolf · 2020-01-17T13:17:33Z

If this feature was requested by users we should rather keep it by doing a server-side sort. We would eventually like to stream these results to support huge exports but there's no immediate timeline for implementing that.

I have update to sort server-side.

I think doing this with ES does make more sense, but we would need another field to sort-by. We need to either copy _id to something with doc_values enabled, or find another field to sort by. I think finding another field would make sense but would be a breaking chance since the order would change. We should consider having a created_at field which is automatically populated which we could then sort by.

This sounds like a good idea.

Discussed with @mikecote who recommended we just sort the ES response in fetchObjectsToExport where the ES sort was removed. sortObjects is sorting for priority of dependencies, which will take precedence but still result in consistent results.

There previously was only coverage when objects were provided, resulting in the bulk request - so this also has the benefit of including that path using find.

Ah I missed that 👍

@mikecote, do you want this backported to 7.x - or just leave it at 8.0?

I don't see why not, might as well backport this to 7.x.
