I'm using Talend Open Studio from 2 years now and its perfect to integrate files with your BDD.

I've done many applications with this ETL in order to read from a file and write the data in a BDD (one or many BDD to write in the same job). Very good software

Pros

Easy to use No need to "hard" code in order to have your job done Easy to integrate with many technologies of BDD (MySQL, noSql and many more) Easy to integrate with many kind of files (csv, xls, xlsx) There's a lot of forum with people that's willing to help if you know how to ask

Cons

There's a lot of components, in order to manage everything in this software you will have to do to many formations.

Enterprise Level Data Integration Software

Our big data projects are based on Talend platform for our pipeline processing. To handle the exception properly, we designed a complex multi-master handling process to make sure the runtime exception can be resumed automatically. Other than that, Talend fulfilled our needs properly and their support were cooperative and working hard.

Pros

1. Open source; 2. Full of transformations to support different scenarios; 3. Convenient designer/java code switching capability for troubleshooting; 4. Integrated with java, maven, nexus; 5. Integration support with Big Data and MDM.

Cons

1. When project is big, the designer is becoming slower and slower; 2. The exception handling not convenient. You can either let go the exception or stop the process, or using external controller to resume the applications. But you cannot customize the try catch block of the exception itself; 3. Nexus integration is buggy on talend 7.

Very time-efficient

Pros

Manages and transfers large data batches quickly ,this also applies to full migrations . The UI is easy to use and so is accessing relevant components .

Cons

Data Fabric / Talend is really heavy to run and requires a lot of computing power .There is also a lot to learn when you are starting out with it .

Use talend in the company to implement integrations between systems.Using both Web services and file

Pros

Ease of learning. Development can be done by writing a few lines of code or in any case with very basic java knowledge. Graphically it is possible to write writes or readings in the database, writings or readings on file. Talend already provides default connectors with other systems. Such as Google Cloud, Excel, MySql, Oracle and many others.

Cons

The version for mac is horrible. Sometimes you have to use "Ctrl" sometimes "Cmd" is really badly done. In my experiences the speed of learning clashes with the consumption of resources and the slowness of the interfaces. An interface made in pure Java requires more time to implement but is definitely more performing.

When you need to beam your data from one database or format to any other format or database

Talend Data Integration is an open source application, available in free and paid premium versions, which saves an enormous amount of time and provides you with the ability to setup and automate most of the work needed to sync data from one application or database to another application or database. It's easy to drag an drop lines between pre built components for almost every data base or format or data source known to mankind, click automap to map the corresponding fields. The paid version is great because of the level of support provided by the company, plus they also offer hosting and team collaboration features to let a group of people share with their fellow team members any recipes for extracting and loading data.

Pros

Talend Data Integration has a great set of features. Plus, the company behind the software has earned one of the best reputations and most respect in the realm of data integration and big data. The software user interface is very good to great and takes a short time to explore and get used to it. There is an online community for discussing with other users, or plenty of consultants and developers available if you want to outsource that work. Based on java, it's industrial strength and and army of java pros is available if and when you want.

Cons

Talend is a Windows desktop app running on top of the Eclipse development environment, so you need a several hundred MB of ram and disk space to run the application comfortably.
