You must have faced a situation in your Job designing career where you have to deal with an ever-changing schema of the input source. Whether the data coming from a database or a simple input file, you can't define the metadata for it. When you don't define schema, the system won't be able to read it properly.The only solution to this problem is to define Runtime schema. The Runtime schema is being created and read at the run time. But, the question is how to do it in Talend ?

Requirement :

The requirement is to read the data from a table and store it in a file. And, the table structure is unknown. Means, we can't define the metadata structure. 

What is Dynamic Schema ?

Dynamic schema allows you to design Jobs with an unknown column structure (unknown name and number of columns). If necessary, dynamic columns can be mapped directly to the target using Pass-through mode. For example, if you need to migrate a whole database with hundreds of tables, you can do so without explicitly including the table structure, using a single Job.

Can we define schema at Runtime ?

The Short answer is NO. We can't define a dynamic schema. All schema must be defined at the time of component designing whether Repository or Built In.

But, there is one feature available in Talend Open Studio Enterprise version , not in the Community version, which solves this problem. I don't have subscribed version of Talend, so, I am going to use screenshots from the Talend's web site.

How To Process Changing Data Structure ?

Read a Table with Dynamic Schema :

In this example, we are going to read and extract the table records and populate an output file without defining the metadata structure.

In Talend Open Studio for Data Integration, the community version, you have to define each column in the schema to map the real table structure. If the table structure is unknown, it is impossible to read the table.

Using this type, you just need to define only one column with the Dynamic type instead of defining all columns.

The Job Design :

The Job design is very simple. Just one tMysqlInput component to read the table from database and one tFileOutputDelimited component to capture the output.

tMysqlInput Component Configuration : 

In this , we are going to read a table Person. The query type is Built-in as we are hard coding the statement and also the schema is Built In. Just for the reference, the table contents are like this :

tMySqlInput Schema :

The Talend Community edition requires you to define the metadata for all columns under the Built-In schema but in the Enterprise edition, you can just define the Type as Dynamic and  that's it.

tFileOutputDelimited Component Configuration :

You can configure this component based on your requirement. If you want to include table columns in the output, you can just check Include Header box. Also, select Built In schema and just click on Sync columns to use the same schema as used by linked components. In this way, you don't have to define it again and again.

The Final Job Execution :

Once you execute the job finally, it will have the records with the header details as shown below. The one thing to notice here, we haven't defined any schema for the output file.

This is another very common scenario. We have this common requirement of combining data from multiple sources and insert it into one destination. The destination could be one file or database.In this post, I will cover how to combine data from multiple sources. The condition is that the SCHEMA must be same of all the input sources. Talend provides a component for this : tUnite. If you are aware of the Datastage ETL tool then it's more like a FUNNEL stage.

The Requirement 

The requirement is to take data from 4 input files, combine it and present it as a single output. For this demo, I will be taking data from multiple files and insert it into one file.

Steps To Combine Data Into One File :

  • The first step is to take the input files. Based on your input file requirement, you can select the Talend component. As I am dealing with text files in this demo, I will take tFileInputDelimited component. There are two ways to design job for this job. 

First Job Design :

In this design, you can take the input files separately and take the tFileInputDelimited component for each file. But this is not good when you have to deal with a large number of files. The benefit of using this is that you can define the order in which the input files should get processed. 

Second Job Design :

In this design, you can deal with the multiple files at once. Using tFileList component, you can iterate through the files at once and you don't have to use multiple tFileInputDelimited components.

If you are not sure how to use tFileList component then please check this tutorial :

  • While reading the records from input file, you must define the schema. We can define the schema in two ways either through Repository or Built In option. When you are defining schema through Repository, you always have to describe it first under Metadata and it will get stored there. Whereas the Built In schema doesn't get stored anywhere and you can define it at the time of component configuration.

  • The next is to use tUnite component, to combine files coming from multiple sources. The one thing that you have to consider here is the schema must be same in all the input files. The component configuration is also very simple. You just have to click on Sync column option to get the schema of the input component.

  • As soon as you link the tUnite component to another output component(tFileOutputDelimited), the same schema structure would get propagated to the output also.If you don't have any specific requirement of output then you don't have to do anything extra other than just connecting the tUnite component to the tFileOutputDelimited component.

Final Job Execution

There are multiple scenarios where looping is required. The looping concept is present in all programming language and you must have used it somewhere. The question is how to use it in Talend? Fortunately, Talend provides a lof of looping components for this purpose. And, if any of the components is not able to fulfill your requirement then you can also write your custom code.

Looping Components Available In Talend


This component is same as your programming language loop. You can define the Start and End of the loop with the incremented step. It operates on the task execution. It allows you to execute a task or job automatically based on a loop.tLoop is to be used as a start component and can only be used with an iterate connection to the next component.You can loop through either using FOR or WHILE loop.

Get more details here : tLoop Component Details

For Loop Settings :

While Loop Settings :

tLoop In Action 

In simple terms, we can use this to iterate a job n number of times. There could be a requirement to execute a specific job multiple times, so instead of calling it multiple times , we can just pass it in the tLoop. So, basically, it works on Parent and Child relationship. The job where the tLoop component is being used, will work as the Parent component. 

For the demo, I am going to use one of  the existing jobs ( HowToReadMultipleFiles ). This job will work as a child because it will be called by a tLoop job multiple times. 

Child Job 

Parent Job

Final Job Execution :

tLoop Component :

tRunJob Component :

tSleep Component :

We are going to call our child Job 3 times as per our Loop settings. And in one run , this child job prints 4 lines at the console so it means at the end of our Parent job run, we will see 12 lines of output on the console.


tForeach creates a loop on a list for an iterate link. tForeach allows you to to create a loop on a list for an iterate link. tForeach is an input component and requires an Iterate link to connect it to another component. You can insert any value in the double quotes to be iterated upon.

Get more details here : tForEach Component Details

tForEach In Action

For the demo purpose, I have created a simple Job here. We are going to iterate above defined value in the tForEach settings. Will just display the records on the console using tJava component. tJava component is required when we have to write our custom code. As you could have guessed it already, this should be written in Java.

tJava Component 

This component has an only window : Code. You can write your desired Java code here and this component will execute it.

tForEach Job Execution :


This component is important when we have to loop through the directories and files. tFileList retrieves a set of files or folders based on a filemask pattern and iterates on each unity. I have covered this component in detail in one of my previous post with the job execution.

Please find the detail here : Job execution with tFileList component

Till now, we have been reading single Excel and Delimited file. In this Talend tutorial for beginners, we will be reading multiple files using tFileList  Talend component.

Requirement :

The requirement is to read multiple text files present in the folder. In this demo tutorial, we will read multiple files available in a folder, pass these files as input and read the contents of the files and display the contents on the console.

Steps To Read Multiple Files At Once :

  • Let's have a look at our input files first. For this demo, I have created a folder and put 4 four files under it. You can write anything under it. All these contents will be displayed on the console once we run our job.
  • As far as the contents are concerned, I have put just one line in all input files. 

  • The final job design will be as shown in the below screenshot. As you can see in the screenshot, I have created a new job HowToReadMultipleFiles. The job creation process is same as used in the previous tutorials. I have used only 3 components here : tFileList_1, tFileInputDelimited_1 and tLogRow_1.

  • First thing first, to read multiple files, we have to configure the tFileList_1 component. Browse for the directory where your files are present. Next, you have to select FileList type, you will get 3 options ( Files, Directories and Both) in the drop down list. Based on your requirement, you can select any one of it.

Global Parameter To Consider While Using tFileList_1 :

As we are reading the files dynamically, we have to pass dynamic values instead of fixed file name.
Global parameters help us to resolve this problem. Based on your requirement, you can take any of the values and use it to the files dynamically.

  • This variable holds current file name without complete path.

  • This variables holds current file name with complete path.

  • This variable holds current file`s extension, if file has no extension then it will return null

  • This variable holds only directory name with path exclude file name.

  • This variables holds the number of files listed by tFilelist.
  • In my job design, I use ((String)globalMap.get("tFileList_1_CURRENT_FILEPATH")) as the file name must be there with its directory path. The System must know where your files are located. This parameter is being used in the tFileInputDelimited component. As this is the place where we mention the input file names and path. If you want to read excel files then you can use tFileInputExcel in place of tFileInputDelimited.. 

  • You don't have to do any modification in tLogRow. Just link this component with the tInputFileDemilited component and rest will be taken care of automatically.

Talend Components Used In the Design :


tFileList iterates on files or folders of a set directory. tFileList retrieves a set of files or folders based on a filemask pattern and iterates on each unity.

What Is Adjudication ?

Every claim submitted undergoes a process made up of procedures designed to judge how it should be paid - or not - known as adjudication. Each filed claim undergoes the Adjudication process, this step is important to determine the status of the claims. The status may go to Pend status if there is any problem in the claim. In that case, the Claim don't get processed, it goes back to the team for the examination. Millions of claims get processed each day by insurance companies, so, it's not done manually. There are a lot of  Claim Processing Softwares or Tools are available in the market. And, the success rate of all these tools is different. Once the Claim goes into the Pend status, it gets checked manually. Once the error gets corrected, it gets filed again and it has to go through the Adjudication process again.

Claim Adjudication 

Claim Adjudication is not the simple process. There are a lot of steps involved in it. Different claim Processing Softwares has different logic to adjudicate the claims but there are certain steps and all Claim processing tools have to operate in this order only.

Claim Adjudication Step 1 :

The first step is to determine the Member and Provider Status. A Member is someone who receives the service and the Provider is someone who provides the service. So, once the Claim gets filed , the first step is to ensure the validity of the Members and Providers. If the Member is not enrolled in the Plan then this Claim will get rejected.Also, the Plan should be active. If the Plan gets termed and the there is no question of filing the Claim. All these variables get validated and checked with the Software Processing software.

Claim Adjudication Step 2 

Each plan has benefit packages for the Subscribers of the plan. The Member will get benefitted only for the benefit packages covered under his plan. If the rendered service is out of the Member's package, the Claim won't get paid. So, in the 2nd step, the performed HealthCare Service is authorized.The health plans pay benefits only for healthcare services that are medically necessary and appropriate It reduces a plan’s medical malpractice liability : A plan can be liable for the negligent acts of its employees or medical staff and in some cases contracted providers.So, it must take measures to ensure that the care they provide is appropriate.

Claim Adjudication Step 3

Clinical edits are typically supplied by an external vendor whose software specializes in healthcare codes and is integrated with the health plan’s claims system. Also, for some plan, there may be some referral requirements, all these requirements must be met before being the Claim being paid.

Claim Adjudication Step 4

The last step is to determine the Amount, that will get paid to the service provider. There are many factors involved in this also as Deductible, Copayment, Coinsurance. Based on all these factors, the amount gets calculated and paid to the Providers.This step also inspects the possibility of the fraud.If the information is not complete for the provided service then the Claim gets examined and in a case of any kind of fraud, it doesn't get paid.
