Limitations of mongodb sorting
- Sort up to 32 keys
- sort consistency
The sorting consistency means that if the sorted field values are repeated, data duplication may occur when performing pagination queries, that is, the first page and the second page may have the same data.
Then there are two solutions to this problem
- Use unique values for sorting, such as id, etc.
- Use the _id generated by mongodb by default for sorting
db.restaurants.find().sort( {
"borough": 1, "_id": 1 } )
