What are some effective indexing strategies in NoSQL databases?

In NoSQL databases, effective indexing strategies include using primary keys, secondary indexes, and composite indexes. Each has its use cases depending on the query patterns.

Can you explain the difference between primary and secondary indexes?

Sure! A primary index is created on the primary key of a document, ensuring fast access. A secondary index, however, is created on non-primary key fields to optimize queries that filter on those fields.

What are composite indexes and when should I use them?

Composite indexes are indexes on multiple fields. They are useful when you frequently query using multiple attributes, as they can significantly speed up those queries.

Are there any downsides to using too many indexes?

Yes, having too many indexes can lead to increased storage costs and slower write operations, as each index needs to be updated with every write.
