In PostgreSQL, replication lag can occur due to various reasons such as network latency, slow disk I/O, long-running transactions, etc. Replication lag can occur due to various reasons, such as: Network latency: Network latency is the delay caused by the time it takes for data to travel between the primary and standby databases.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. It was a great privilege. Ford, et al., “TCP

MySQL, as well as other RDBMS, are designed to work respecting the model and cannot scale in any way by fragmenting and distributing a schema, so what can be done to scale? Let’s see the write operations with 24 and 64 threads: We get a gain of ~33% just using sharding, while for latency, we do not have a cost. eu-central-1.elb.amazonaws.com
