I will post a couple queries to help with this.
Get number of queued posts
db.objects.count({_key: "post:queue"});Get latest 20 post queue objects ids
db.objects.find({_key: "post:queue"}).sort({score: -1}).limit(20);Using ids from above query you can get the queued posts with
db.objects.find({_key: "post:queue:<replace_with_id_from_above_query"});To delete a post queue from the db with id 123456
db.objects.remove({_key: "post:queue", value: "123456"}); db.objects.remove({_key: "post:queue:123456"});To remove all queued posts
db.objects.remove({_key: /^post:queue/});Hope that helps.
