SQL Server 8060 row size query limit

Posted by jpluimers on 2019/06/19

Every now and then you bump into a limit you did not know it existed before:

Cannot create a row of size 8209 which is greater than the allowable maximum row size of 8060.

This is while querying a few tables having a combined column size of more than 8060. Which means it is not just about single tables being too wide.

Pattern: Service Mesh

Posted by jpluimers on 2019/06/19

I need to re-read this: [WayBackPattern: Service Mesh

Via [WayBack] What is a Service Mesh? What is the purpose of Istio? – The Isoblog. /[Archive.is] What is a Service Mesh? What is the purpose of Istio in Kubernetes? … – Kristian Köhntopp – Google+:

An article by Phil Calçado explains the Container Pattern “Service Mesh” and why one would want that in a really nice way.

Phil uses early networking as an example, and explains how common functionality needed in all applications was abstracted out of the application code and moved into the network stack, forming the TCP flow control layer we have in todays networking.

A similar thing is happening with other functionality that all services that do a form of remote procedure call have to have, and we are moving this into a different layer. He then gives examples of the ongoing evolution of that layer, from Finagle and Proxygen through Synapse and Nerve, Prana, Eureka and Linkerd. Envoy and the resulting Istio project of CNCF are the current result of that development, but the topic is under research, still.
