| Description |
|
$indexStats tells you how many times each index was used in a query. We need to make sure queries generated by Bonsai are included in these counts. (We don't need to support the $indexStats operator itself.) This may be working already; I'm not sure. With CQF enabled this assertion fails, but that could be because Bonsai is choosing a different plan which doesn't use the expected index. |
