Select and join Action

You have more action that you will do on arrays. So Select allows you to go ahead and if you have an array of objects and you have ABCD as properties of that object. You get to select A and B and you get new array with Properties A and B then join action is that lets you take an array of strings or objects. You can use delimiter and you can join and create a string out of those entries in that array. It is very useful one of new connectors is the computer version service witch is one of cognitive services one of the operation that describes an image give you all tags, it’s like an image has dog, it has building and all these things select and join. In case of tags you can filter them and you can turn into new string that you can send in an email.

Retry information in History

What is happening in the background? How long it took time? What errors you are getting in the intermediate calls? If you go to update something in MS Dynamics and MS Dynamics is down for a sub seconds instead of you just saying, you don’t get your update, we will go and we will retry it with retry polices. Now you can actually see what actually happened behind. You can retry three times.

Service Bus Sessions

Service bus session allows to do thing like correlation and sequential convoys for all your biz talk historians out there. Now you can do that in logic apps which uses the sequential convoy.

Sequential convoy is ability to have in order correlated messages locked to particular logic app instance so that no other logic app instance can get the message correlated to that. This is called a convoy set of correlated messages, so all go to one instance. When you lock that convoy, which is using for session, that logic app continue the process to all the messages that related to that context.

Release Notes on Blade

Now right from the management portal you go click on release node and you can see a blade of history of all logic app releases and find what new feature have been added.

Run After Configuration in Designer

You can configure your action to determine when it will run. So usually you know if you look at code view we see run after success is the default setting but some time you want to have an exception handling so now you can have a run after Success branch and run after failure branch then react to the different items. Now in the blade you hit the … in the action and you get chose the reaction that you run after the previous step. There is some styling too when the run after failed then the arrow is different. You can tell which one is catching an exception.
