What is most valuable?
It provides the power of an ETL tool but packaged as a Java app without needing any custom product setup. This has helped us handle several of our data integration/migration needs (including the ones needed for our in-house products), without worrying about alignment to our clients' tech infrastructure as long as they are fine to run a Java app.
Its data integration features are as powerful as any other leading product in this space.
How has it helped my organization?
It improved productivity compared to lot of custom SQL data integrations done before, and at a very low cost. Its HTML document generation feature has helped us ensure documentation of all the ETL code.
What needs improvement?
The open-source version has obviously fewer features compared to the enterprise edition. Specifically, the scheduler, rules engine, etc., are really not available, but these are nice-to-have's for a general ETL development where organizations could address these with other tool sets.
Developers need some experience to gain optimal performance and, being a Java application, tuning knowledge of Java apps helps, which is sometimes difficult for a pure ETL developer.
For how long have I used the solution?
I have used it for more than a year now.
What was my experience with deployment of the solution?
Version 5.6 works best with Java 7 and quite unstable with 8. I encountered a few issues with the multi-threading function leading to DB connection issues.
What do I think about the scalability of the solution?
I have encountered scalability issues; it requires a bit of tuning before we get to optimal performance.
How are customer service and technical support?
I have not used customer service that much. Technical Support
Being open source, technical support is through the Talend forum, which is quite good.
Which solution did I use previously and why did I switch?
I previously used a different solution., and switched because it offered comparable product features at a lower cost.
How was the initial setup?
Initial setup was not difficult.
What about the implementation team?
An in-house team implemented it.
What's my experience with pricing, setup cost, and licensing?
Most of the features are available in the open source version. Only if used in a large enterprise with distributed teams, would we need the licensed version with collaborative development features (repository), schedulers, etc.
