Expert Insights

According to experts, the concept of scalability is not binary, but rather a continuum. As one expert notes:

‘Scale’ isn’t a binary, it’s a continuum. ‘Scales to 60K/s’ can be 5 orders of magnitude more than one system needs and 5 orders of magnitude too small for another.

Another expert highlights the importance of considering the system’s needs and the potential drawbacks of over-scaling:

Bringing in the overhead and management issues of the super scalable techs, as well as their limitations they impose so that they can scale, to a system that would actually be better off with a richer model whose richness prevents it from scaling but would save a lot of effort is also a bad choice.

Real-World Applications

Some experts have found success using Postgres LISTEN/NOTIFY in their projects, citing its integration with the rest of the database and ease of use as major advantages.
