The video begins by addressing the challenge of high read volumes in scalable systems []. To counter the mismatch between frequent reads and infrequent writes, the solution is caching, where data is first checked in a fast cache layer before accessing the slower database []. While this significantly reduces database load, maintaining cache consistency and managing expiration are key considerations, often addressed with strategies like TTL or write-through caching using tools like Redis or Memcached [].
