During the keynote at MDBW, we had an issue during the creation of a wildcard index: https://youtu.be/SODvhxJnAcI?t=3003
Here is how I could reproduce it twice and then never again:
Compass 1.19:
- compass-data-sets, sample_airbnb. listingsAndReviews
- Create index named "wildcard", index definition [$**] - [1 (asc)]
- Click "Create index"
- shows error in the screenshots.
Then Compass master:
- delete "wildcard" on sample_airbnb. listingsAndReviews
- Create index named "wildcard", index definition [$**] - [1 (asc)]
- Click "Create index"
- shows timeout error
In both cases the index is created.
Note that this is not specific to wildcard indexes: other users had errors with regular indexes too.
