elements - elements held at the latest measurement
firstElements - elements held when the run of growth began
growthSamples - measurements at which the collection had grown, since it last shrank or was first seen
firstSeen - when the run of growth began
lastGrew - the latest measurement that found it grown
sessionId - the session, hashed unless insight details are enabled
uiId - the UI within the session
public record GrowingViewState(String viewClass, String field, @Nullable String route, int elements, int firstElements, int growthSamples, Instant firstSeen, Instant lastGrew, @Nullable String sessionId, int uiId) extends Record
A collection one view instance keeps in a field, which has grown at every measurement of its UI that saw it change — the shape of a view accumulating what it loads instead of replacing it.
