New Lightning Components - Winter19

lightning:empApi
Embed the lightning:empApi component in your custom Lightning component to subscribe to a streaming event channel and receive event notifications. You can subscribe to any type of event channel on the Lightning Platform, including channels for platform events, PushTopic and generic events, and Change Data Capture (Developer Preview) events. The lightning:empApi component uses a shared CometD-based Streaming API connection, enabling you to run multiple streaming apps in the browser.
lightning:map
The lightning:map component securely displays a map of one or more locations using Google Maps. You can pass markers to the component to define the locations to map. A marker can be a coordinate pair of latitude and longitude, or a set of address elements: City, Country, PostalCode, State, and Street.
Here’s the map component with one address.

When you specify multiple locations, the map component creates clickable tiles for each location. You can specify a title to display above the list of addresses. You can also show a footer with an “Open in Google Maps” link and specify an initial zoom level for the map.
lightning:menuDivider
This component is used as a child component of lightning:buttonMenu. Use lightning:menuDivider to create a dividing line after a menu item. By default, space is added above and below the divider. Use variant="compact" with lightning:menuDivider to reduce the space.


lightning:menuSubheader
This component is used as a child component of lightning:buttonMenu. Use lightning:menuSubheader to create subheadings in the list of menu items. Specify the text of the heading using the label attribute.

Mashup Integration in Salesforce

During preparation for TA certification exam, I came across a word Mashup for integration a number of times. I explored about it and below is description:- Mashups, sometimes called “composites,” are hybrid applications created by bringing together several data sources and Web services to create a new application or to add value to an existing application. Behind the scenes, mashups may require different levels of integration, depending on whether the mashed-up data is only meant to be viewed, whether it can be edited, and whether data is actually transferred between systems. There are three types of mashup:- Client Presentation Mashup - In this type of mashup the integration takes place strictly at the visual level. It makes possible to view data from two or more applications in a browser,  without actually moving data between the applications. Example - Google Maps. Client Service Mashup - As mashups evolve, they are becoming more complex and sophisticated. Client ser

Grant Access Using Hierarchies

Problem There is a custom object say 'XYZ' and OWD for this is set to ' Private ', which means record of this can be seen by only owner and users above in role-hierarchy and territory. However, to share this with other user, we can manually share it. The problem is that I don't want other users, who are above in role-hierarchy and territory of the user with whom record has shared, can see it.

ReadOnly Annotation

Use Case:- You want to show up to 10000 record on single VF page. Count of records based upon some business requirement where number of records could go up to 1 million. So far, it was not possible to achieve above in VF page because of following limitations:- The maximum number of items in a collection that can be iterated over using components such as <apex:dataTable> , <apex:dataList> , and <apex:repeat> is 1000. Normally, queries for a single Visualforce page request may not retrieve more than 50,000 rows. Solution:- But with API version 23.0 , salesforce has introduced ' ReadOnly ' annotation which has following functionality/restriction:- The @ReadOnly annotation allows you to perform unrestricted queries against the Force.comdatabase. All other limits still apply. It's important to note that this annotation, while removing the limit of the number of returned rows for a request, blocks you from performing the following operations
