Biggest concern I have about all these hosted Redis replacements is that of latency.
I use Redis on a highly controlled internal network and also local for its speed... This goes when moving to a hosted solution.
- jkaplowitz 8y agoIf you're already accessing it from within GCP, their network is excellent, not much lower latency than a high-quality internal physical network (under an order of magnitude) and highly flexible and configurable. In that use case it should be comparable to any solution you can host within GCP except hosting on the same instance as each client and using loopback access. For accessing from outside GCP, yeah the broader internet latency would figure into this as any other external solution.
- edf13 8y agoIt depends on what you mean by not much lower latency though... At Redis speeds the network latency can quite often be the bottleneck.
- jkaplowitz 8y agoDouble digits of microseconds of difference as of some time last year, if I remember correctly - it might have gotten even better since then since I know Google wanted to narrow that gap. (Disclaimer: While I have in the past worked for the GCP team, nothing in this comment relates to my time at Google or to info I learned then.)
