[FEATURE] Support cumulative_sum aggregations

[hughbe]

I’m trying to migrate a library from 7.x to 8.x. However, I cannot find support the cumulative_sum aggregation in the new version of the library.

Will support for this aggregation be added?

Hi, @hughbe.

This is not currently available in the 8.0.0 as documented in our supported aggregations in our release notes. We will (re)introduce this (and other) aggregation types in future client releases. Thanks for raising your need for this type, as it helps prioritise that work.
