Caching involves storing the results of expensive query operations in memory, which can significantly reduce query latency and improve throughput by avoiding repeated computations.

Caching is identical to indexing in that both techniques aim to reduce query latency, but caching is more effective for write-heavy workloads.

Caching should be avoided as it consumes memory resources without providing any performance benefits.

Caching is primarily used for data storage and has no impact on query performance.
