[Maps] Keep lines on Point to Point layers visible as user zooms in

[kindsun]

Describe the feature:

When filtering a Point to Point (pew pew) Layer by map bounds, either prevent filtering or allow a user to configure whether or not lines are filtered out.

I believe this was discussed when Point to Point layers was originally introduced, but I don't see it captured in writing anywhere. It's also possible that it was tabled pending a better solution for storing and retrieving lines on the ES side, which has been captured here. This solution would likely be a lot cleaner vs. creating the lines on-the-fly on the client side (as we do now) and excepting points from geo_bounding_box filters.

Also related: #31396

Describe a specific use case for the feature:

Any time a user wants to zoom in on a Map point feature connected by lines and wants that line to stay present for context. Also any time the lines themselves may be of primary interest and a user wants to zoom in on a cluster or intersection of them.

Point2point needs to balance multiple conflicting requirements:

• high precision zoomed in vs low prevision zoomed out
• constraining the aggregation size using bounded query vs showing lines out-of-bounds for context

This ticket essentially asks for removing the bounds-filter from the request. This has the potential of vastly increasing the bucket-limit for high precision request (e.g. zoomed in).

Additional write-up here #46515 (comment)

Not sure what the "best" approach is here.

The solution might just be to wait for elastic/elasticsearch#41649, at which point the nature of point to point either changes to use geo_lines or gets deprecated in favor of that layer type

Not sure geoline will provide any help in this case. Geoline connects multiple documents into a line. Point2point connects aggregated source and destinations where source and destination come from a single document.

Unless there were a reindexing step? A user might be interested in pulling that data out into a separate index

Closing, no clear solution since too This ticket essentially asks for removing the bounds-filter from the request. This has the potential of vastly increasing the bucket-limit for high precision request (e.g. zoomed in).
