Calculate views aggregations after the query.
Has additional grouping/aggregation features vs core.
Can do grouping functions, or column aggregation in header/footer.
Some things work well, but there are some major issues.
There seems to be some interest, but not a lot of development activity.
Aggregation in views can get pretty complicated. The API is very powerful, but the UI is limited so it's easy to run into confusing blockers.
MR36 in https://www.drupal.org/project/views_aggregator/issues/3482129 is pretty important.
Submodule views_aggregator_more_functions has sequence number, range diff, and percentage.
Issues
Calculation on custom view field created by plugin
Add ability to force use rendered field in comparing for sorting
[META] Fix separators / decimals calculations
How to format column aggregation totals?
Table::getCellRaw(): Return value must be of type string, false returned
Crashes with Drupal\views_aggregator\Plugin\views\style\Table::setAggregatedGroupValues(): Argument #3 ($group_aggregation_results) must be of type int, string given
