How to create an effective Index with this query?

Will MongoDB 's flexible query feature create many index data and occupy large disk space?

  • Answer:

    You control the indexes that are created, so you control the space used. Compare MongoDB to a Key/Value store (like Membase). Membase has exactly one index: ID. MongoDB has at least one index: ID. But you can add secondary indexes. Just like an SQL DB, these indexes are not free. They will consume memory and disk space. So it is up to you to make the trade-offs.
