What are the ways to increase performance and storage capacity in NoSQL databases?

Several approaches can be used to increase performance and storage capacity in NoSQL databases:

1. Sharding — horizontal partitioning of data into parts (shards) stored on different servers. This helps distribute the load and increase storage capacity.

2. Replication — creating copies of data on multiple nodes to enhance availability and fault tolerance.

3. Using data compression — many NoSQL databases support compression, which reduces the space occupied.

4. Optimizing data structure — choosing an appropriate storage format (e.g., documents, key-value, graphs) and proper indexing to speed up queries.

5. Caching — using built-in or external caches to reduce database load.

6. Configuring parameters — for example, increasing buffer sizes, tuning read/write settings.

These methods help scale NoSQL databases and improve their performance and storage capacity.
