How can I write this expression in mule 4 migrating from mule 3 - mulesoft

I am migrating mule 3 code to mule 4 and this is the code in Expression component .How can I migrate this into mule 4.
{
vars.MessageArray = new java.util.ArrayList();
vars.combinedArray = new java.util.ArrayList();
}
I am new to Mulesoft, and working on migration. I search around for above problem but I didn't got the correct answer. Can anyone help me what should I do in this?


This is just setting to vars to an empty Array. You can just two set-variable to set these variables and give the value []
For example:
<set-variable value="#[]" doc:name="combinedArray" variableName="combinedArray"/>

How can we initialize DataChangeDetectionPolicy using .netsdk?

I have created a new index that is populated using an indexer. The indexer's datasource is a SQL view that has a Timestamp column of type datetime. Since we don't want a full reindexing each time the indexer runs, this column should be used to determine which data have changed since the last indexer run.
According to the documentation we need to create or update the datasource by setting the HighWatermarkColumnName and ODataType to the DataChangeDetectionPolicy object. The example in the documentation uses the REST API and there is also way to do it using the azure search portal directly.
However I want to do it using .netsdk and so far I haven't been able to do so. I am using Azure.Search.Documents(11.2.0 - beta.2). Here is the part of the code I use to create the datasource:
SearchIndexerDataSourceConnection CreateIndexerDataSource()
{
var ds = new SearchIndexerDataSourceConnection(DATASOURCE,
SearchIndexerDataSourceType.AzureSql,
this._datasourceConStringMaxEvents,
new SearchIndexerDataContainer(SQLVIEW));
//ds.DataChangeDetectionPolicy = new DataChangeDetectionPolicy();
return ds;
}
The commented code is what I tried to do to initialize the DataChangeDetectionPolicy but there is no ctor exposed. Am I missing something?
Thanks in advance.

Instead of using DataChangeDetectionPolicy, you will need to use HighWaterMarkChangeDetectionPolicy which is derived from DataChangeDetectionPolicy.
So your code would be something like:
ds.DataChangeDetectionPolicy = new HighWaterMarkChangeDetectionPolicy("Timestamp");

Want to pass in a string array into a WS.sendRequest using groovy

I am new to API testing and am using Katalon to develop the tests. I've Googled any question I could think of and couldn't find anything to answer my question.
We have an API with the following Body
[
"${idValue1}",
"${idValue2}",
"${idValue3}",
"${idValue4}",
"${idValue5}",
]
I believe the purpose of this one is to delete multiple records at once by id. The script that we have in the step definition is
response = WS.sendRequest(findTestObject('EquipmentAPI/data-objects/DELETE Equipment By Ids', [('host') : GlobalVariable.host, ('idValues') : GlobalVariable.equipId]))
GlobalVariable.equipId = WS.getElementPropertyValue(response, 'data[0].id')
There are other step definitions that run before this one to set the Global Variables for use. I was able to generate the string array without issue.
Is this something that's possible? Please help!
Please let me know if further information is needed. Thanks.

Use content of a tuple as variable session

I extracted from a previous response an Object of tuple with the following regex :
.check(regex(""""idSc":(.{1,8}),"pasTemps":."codePasTemps":(.),"""").ofType[(String,String)].findAll.saveAs ("OBJECTS1"))
So I get my object :
OBJECTS1 -> List((1657751,2), (1658105,2), (4557378,2), (1657750,1), (916,1), (917,2), (1658068,1), (1658069,2), (4557379,2), (1658082,1), (4557367,1), (4557368,1), (1660865,2), (1660866,2), (1658122,1), (921,1), (922,2), (923,2), (1660875,1), (1660876,2), (1660877,2), (1658300,1), (1658301,1), (1658302,1), (1658309,1), (1658310,1), (2996562,1), (4638455,1))
After that I did a Foreach and need to extract every couple to add them in next requests So we tried :
.foreach("${OBJECTS1}", "couple") {
exec(http("request_foreach47"
.get("/ctr/web/api/seriegraph/bydates/${couple(0)}/${couple(1)}/1552863600000/1554191743799")
.headers(headers_27))
}
But I get the message : named 'couple' does not support index access
I also though that to use 2 regex on the couple to extract both part could work but I haven't found any way to use a regex on a session variable. (Even if its not needed for this case but possible im really interessed to learn how as it could be usefull)
If would be really thankfull if you could provided me help. (Im using Gatling 2 but can,'t use a more recent version as its for work and others scripts have been develloped with Gatling2)

each "couple" is a scala tuple which can't be indexed into like a collection. Fortunately the gatling EL has a function that handles tuples.
so instead of
.get("/ctr/web/api/seriegraph/bydates/${couple(0)}/${couple(1)}/1552863600000/1554191743799")
you can use
.get("/ctr/web/api/seriegraph/bydates/${couple._1}/${couple._2}/1552863600000/1554191743799")

Parsing data from Kafka in Apache Flink

I am just getting started on Apache Flink (Scala API), my issue is following:
I am trying to stream data from Kafka into Apache Flink based on one example from the Flink site:
val stream =
env.addSource(new FlinkKafkaConsumer09("testing", new SimpleStringSchema() , properties))
Everything works correctly, the stream.print() statement displays the following on the screen:
2018-05-16 10:22:44 AM|1|11|-71.16|40.27
I would like to use a case class in order to load the data, I've tried using
flatMap(p=>p.split("|"))
but it's only splitting the data one character at a time.
Basically the expected results is to be able to populate 5 fields of the case class as follows
field(0)=2018-05-16 10:22:44 AM
field(1)=1
field(2)=11
field(3)=-71.16
field(4)=40.27
but it's now doing:
field(0) = 2
field(1) = 0
field(3) = 1
field(4) = 8
etc...
Any advice would be greatly appreciated.
Thank you in advance
Frank

The problem is the usage of String.split. If you call it with a String, then the method expects it to be a regular expression. Thus, p.split("\\|") would be the correct regular expression for your input data. Alternatively, you can also call the split variant where you specify the separating character p.split('|'). Both solutions should give you the desired result.

SubSonic 3.0 two different Databases namespace Issue

My question is simple, I have two databases with the same scehema, one is live database say DLive and other one is testbed say DTestBed....
However, I want to use the same database namespace for both database. How can I achieve that without changing namespace in my code all over? Sometimes you need to do builds for live and testbeds in the same day ! Its really hard to change big project namespaces everytime you build.
How can I just change the webconfig connection string and get it done?
Thanks,

STEP 1:
Open 'Setting.ttinclude' from your Subsonic project..
STEP 2:
Add new vairable beneath 'const string DatabaseName'..
const string DatabaseObjectName = "DatabaseObjectName";// This is the object that you use for calling Stored Procedures, Tables and etc...
like this;
DatabaseObjectNameDB db = new DatabaseObjectNameDB();
STEP 3:
Now open 'ActiveRecord.tt', 'StoredProcedures.tt', 'Context.tt' files from your Subsonic project..
STEP 4:
Replace '<#=DatabaseName#>' with '<#=DatabaseObjectName#>' in above opened files...
STEP 5:
Now 'Run Custom Tools', by Righ-Click your Subsonic project...
Here you go...
Problem solved!!
Regards,
Naeem

Are you using SubSonic2 or three?
With SubSonic 3 it's as simple as this:
var db = new YourProductDB("connectionstringname");
var db = new YourProductDB("Server=localhost;Database=devdb;Uid=root;", "MySql.Data.MySqlClient");
for the first row you have to have both connection strings defined in your web.config/app.config
