Spring Cloud (Netflix) Feign: Use feign to expose services in Dubbo

Requirements Scenario In a micro-service architecture, the way in which a requester of a service invokes a remote service is a problem that must be addressed. In the spring Cloud (Netflix) technology stack, each micro-service is exposed in the form of an HTTP rest interface, which normally requires an HTTP client to be used when executing a remote call, and then an HTTP request to the service. In fact, if you use Netflix's feign as an HTTP client, we

Netflix open source Spring Cloud host-level performance monitoring framework--vector

host is negligible because the customer is responsible for tracking status, sampling rate, and calculation.In addition, metrics are not aggregated across hosts or remain unchanged outside the user's browser session, keeping the framework clear. vector only requires the local browser and PCP installed on the host you wish to monitor. An intermediate collector, server, or database infrastructure is not required.The final monitoring page looks like this:Architecture diagram:To install the PCP:Sour

UnTyped Dataset and Strong-Typed Dataset

Take the table name "MyTable" and the field FirstName varchar (30) and FamilyName varchar (30) as an example. Non-strong (UnTyped) Dataset does not need to define the attributes of each field of the corresponding table in advance, you can directly obtain the values from the queried result set (non-strong (UnTyped) Dataset), for example:String lFirstName =LDs. Table ["MyTable"]. Rows [0] ["FirstName"]. ToStr

What is the higher performance of accessing Typed Dataset than that of untyped dataset?

I have seen many such comments on the Internet,AccessThe performance of Typed Dataset data is higher than that of untyped dataset. I have always been skeptical.
