Sharding splits databases into smaller parts to improve performance and scalability.

Database bottlenecks slow down performance, but identifying them helps optimize and scale effectively.

Transactions ensure database operations are reliable using ACID properties.

Write-Ahead Log ensures data is safely recorded before changes are made.

Database isolation levels determine how transactions interact and affect data consistency.

Cache penetration occurs when requests for non-existent data overload the database.

Cache breakdowns can overwhelm databases, but request coalescing solves this issue.

The Cache-Aside Pattern speeds up data retrieval by using a cache to store frequently accessed data.

Partition pruning helps databases skip unnecessary data scans, speeding up queries.

Cache stampede occurs when many requests hit the database due to a cache miss.
