Compare Get metadata activity with lookup output

I was trying to do a delta load using ADF. I have a get meta data activity on my blob location to read all the files using getchildItem and lookup activity which reads loaded file names from a sql table. Following this I have a filter activity which should filter out the new files from the blob location.
expression on items
#activity('GetRawFilenames').output.childItems
expression on Condition
#not(contains(activity('GetLoadedFilesList').output.value,item().name))
But still its not filtering out the file list in the filter output. Could the experts please help? Thanks in advance..
Have a look at this. They describe same problem. Expression on condition should be:
#not(contains(join(activity('GetLoadedFilesList').output.value,','),item().name))
so after joining of GetLoadedFilesList activity your code should be working

Firestore - saving external links in a document with both url and title

How can I create an array in firestore that can save external links?
I want to save the title and the href so that I can use both values in the read.
I want the links attribute to be an array so that I can save multiple links. Is it possible to do that in a single firebase attribute, or should I create separate link attributes with a href and title for each one (ie firstLinkTitle, firstLinkHref)?
It's not possible to have a number of links, that would be a different array - similar to an array of arrays.
The possibility for the creation of a field of type array for your documents, you can either use the console, where this type is available or via code as the following example:
const data = {
stringExample: 'Example',
arrayExample: ['Title', 'href']
};
const res = await db.collection('data').doc('one').set(data);
With the above example, you should be able to create a field of type array and set the data to it.
Besides that, if you want to update data from your array without uploading all the data again, you can use the function arrayUnion() or use the arrayRemove(), to remove elements from it.
You can get more information on how to work with arrays in Firestore, by checking the below documentation.
Add Data
In case you need something like nested arrays, indeed, you will need to have a "child" collection that will be linked to the father one.
Let me know if the information helped you!

How to create table using json in birt

i am having one column data as JSON format in table. i want to pass that column as report parameter in BIRT. can anyone help me how to parse JSON data and use it in the report.
One way to access the data sent through report parameter is creating a POJO (Plain Old Java Objects) Data Source.
You should create 3 java classes and convert it to jar file and use that as input for POJO Data Source.
Make sure that column names in json file match with the properties you create in java class.
You can refer this video for more info:

Parsing json to Nattable

I have to parse a Json file and show it into a Nattable.
Using this tutorial i am able to parse json and display in Nattable.
But as shown in screenshot for cat column its showing list values as it is .
Is there a way from which i can show list values as Dropdown.
A dropdown in NatTable is intended for editing. I suppose you don't want to support editing but only showing values right? For that you can try to use the TableCellPainter for that column. That painter tries to render the data as subcells in case the data structure is an array or a Collection.
