It is stable. I haven't seen any kind of outages for Talend DQ.

It provides good stability capabilities.

I would rate the stability an eight out of ten.

In redundancy analysis, the query is failing to bring non-matched records. This query is an internal script. There is no way (that I know of) to fix this syntax error for future runs.

It's a stable platform. We process large volumes of data and have not experienced any challenges.

Never had any real issues with the Talend server applications. The only issues we had were related to the limited resources of our development and test environments. Nothing a restart couldn’t fix.

If we encounter issues, it’s most likely when using the Talend Open Studio. The studio can be slow, get stuck, or crash. But again, it can be caused by the resources of your machine or your connection with the repository. If we encounter issues with the Studio we restart the Studio. In emergencies, we create and use a new workspace.

Yes we had issues. Quite often the server needed rebooting as if there were memory leaks. Sometimes the CVS version management got stuck.

No issues

As it is a open source tool, some minor bugs are there.

I did not encounter any stability issues.

Sometimes when working with larger datasets (possibly due to insufficient memory).
