i want to use parallel to mongodb " group by "

fanhongli commented 7 years ago

i found it in mongo_wrapper_meta.c MongoAggregateCount if (bson_iter_init_find(&it, reply, "n")){ count = BsonIterDouble(&it);

that was verry .....

fanhongli commented 7 years ago

it should change to count = BsonIterDouble(&it); if( count==0 ) { count = BsonIterInt32(&it);
}
