Terms in this definition

• Share

  In OpenSharing, the container you fill with tables, views, volumes, models and notebooks for recipients. You need CREATE SHARE on the metastore to make one; add a schema and all its assets, including later ones, go with history.

• Health probe

  A TCP, HTTP or HTTPS check a load balancer uses to decide whether backends are healthy. For an HTTP probe, its path has to return HTTP 200.

• Priority

  Routing method in Traffic Manager for active/passive failover: traffic goes to whichever healthy endpoint has the highest priority.

• Origin

  Host behind Front Door that serves the content, such as an App Service app, storage, a load balancer or any custom host given by FQDN. An App Service app counts as one origin regardless of its worker count.

• PATH

  Parent-child hierarchies in DAX rely on this function. For each row it builds one delimited text value listing the IDs of the row's ancestors, top level first and ending with the row's own ID, which PATHITEM, PATHLENGTH and friends can then pick apart.

Related terms

• Latency sensitivity

  Setting on a Front Door origin group, in milliseconds and 0 by default, that extends the range around the quickest origin; every origin within that range receives traffic according to its weight.

• Route (Front Door)

  In Azure Front Door Standard and Premium, ties a set of domains, protocols and path patterns to one origin group. When matching, an exact path beats any wildcard, and longer wildcards beat shorter ones.

• Rule set (Front Door)

  Rules in Azure Front Door Standard or Premium that run once a route has matched; they can change requests and responses or send traffic to a different origin group.
