Key Takeaways Distributed storage systems benefit organizations by enhancing data availability, fault tolerance, and system scalability, leading to cost savings from reduced hardware needs, energy consumption, and personnel. Variations within these storage systems are called distributed file systems.

DLVs are particularly advantageous for databases with large allocated storage, high I/O per second (IOPS) requirements, or latency-sensitive workloads. The DLV, of course, affects the WRITE operations the most, and hence, the write-only test should be given the most consideration for the comparison of the DLV configuration vs. standard RDS.

Of course, there are “ClientWrite” events, which is the wait event related to writing the data to the client (pg_dump) in this case. Following wait events are captured from a really fast/low latency network. If the network is fast, we may see a good amount of CPU utilization and “DataFileRead” as a wait event.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
