Compression in any database is necessary as it has many advantages, like storage reduction, data transmission time, etc. Storage reduction alone results in significant cost savings, and we can save more data in the same space. When this data block is read, it decompresses it in memory and presents it to the incoming request.

Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. A platform approach, on the other hand, presents a more effective option for understanding observability as a whole. Observability is made up of three key pillars: metrics, logs, and traces.

This means that, if the Cache-Control: max-age=60 header is still present, the cached file’s 60 seconds starts again. If, however, there wasn’t a new file on the server, we’ll bring back a 304 header, no new file, but an entire roundtrip of latency. We can completely cut out the overhead of a roundtrip of latency.
