What are caching mechanisms in databases?
Caching mechanisms in databases are techniques used to store frequently accessed data in memory to speed up retrieval.
How do they improve database performance?
They reduce the need to access slower disk storage by keeping data in faster memory, which significantly speeds up query responses.
Can you give examples of caching mechanisms?
Sure! Common examples include in-memory caches like Redis, Memcached, and database-specific caching like query caching.
What are the potential downsides of using caching?
Potential downsides include stale data if the cache isn't updated properly and increased complexity in cache management.
