Global Data Store & Variable

 The first iFlow shows how to write a variable (Global) and Write the incoming data to a Data Store.

Whereas, in the second iFlow we will fetch data from the data store which was declared in the first iFlow.

Write Variable:

Write Variables are used to share data across different integration flows (deployed on the same tenant).

To consume the variable (either in another step of the same integration flow or in another integration flow), can use a Content Modifier.

A variable gets expired after the retention period which is 400 days.

Data Store Write Operation:

This step performs a Write operation on the transient data store.

Entry ID

Specify an entry ID that is stored together with the message content. The entry ID must not exceed 255 characters. Details for the entry ID are read from the incoming message. You can enter the following kinds of expressions: ${header.headername}, to dynamically generate the entry ID from the message header. ${property.propertyname}, to dynamically generate the entry ID from the exchange property of the message. ${xpath.<xpath>}, to dynamically generate the entry ID from an element in the message indicated by an xPath expression.

Below is Log after Splitter step:

You will observe 18 different Segments for General Splitter in the Trace mode.

Each Splitter consisting of one CustomerReview node.

 

 

 

 

Second iFlow (Consumer)

 

This step selects entries from a transient data store and creates a bulk message containing the data store entries.
